Read Abstract +

Tomographic phase microscopy in cytometry environment is feasible at single cell level and without the a-priori knowledge of the cell orientation. In the present paper we demonstrate different strategies for recovery the rotation angles of single cells and clusters when rotating into microfluidic channels, thus realistically opening to the implementation of marker-free cytofluorimeter for three-dimensional imaging of biological fluids. The pioneering developed strategies allows to measure quantitatively the inner distribution of the refractive indexes inside the cell volume avoiding the use of chemical and fluorescent tags. The imaging apparatus is based on label-free Digital Holography in microscopy setup designed in transmission geometry to image 700x700μm Field of View with lateral resolution of 0.5μm. Digital Holography is perfectly suited for imaging in microchannels as it allows the numerical refocusing of sample into a three-dimensional volume. In the present paper, such imaging arrangement is combined with a high-precision pumping system connected to a microfluidic channel that allow the complete rotation of the flowing cells into the Field of View. High-speed 25Megapixel camera acquires holographic set measurements of all rotating cells that are numerically processed to obtain quantitative two-dimensional phase-contrast maps at different view angles. Accurate numerical algorithms allow to tag each phasecontrast maps with the rotation angle in the microchannel. The couples made of phase-contrast map and measured angle are given as input at tomography algorithms to obtain the refractive index distribution into the cell volume. The approach in principles works properly for any kind of biological matter subjected to rotation as already demonstrated in case of nuclei of plant cells during dehydration. Furthermore, the same approach allows to show the three-dimensional distribution of internalized nano-particles as in case of nano-graphene oxide. The most important achievement and innovation of such strategy is the high-throughput phase-contrast tomography at single cell level that opens to new diagnostic tool thanks to the possibility to have statistically relevant measurement on cell population and also for the possibility to use artificial intelligence architecture for cell identification and classification.

In bone tissue, osteocytes are embedded within a microfluid-filled network which expose them to high levels of fluid shear stress (FSS). The osteocytes’ sensitivity to different levels of FSS has demonstrated. However, there are few attempts to image 3D cellular deformation under FSS by label-free and quantitative microscopy. Digital holographic (DH) microscopy is a powerful imaging technique that can provide rich intracellular information based on the refractive index (RI) contrast, without exogenous contrast agents. However, in DH image recording process, the recorded wave-front contains not only the object’s information but also the aberrations caused by the microscope objective (MO) and the imperfections of optical components of the system. The fitting-based numerical method removes total aberrations by detecting object-free background as reference surfaces. In this paper, we proposed a convolutional neural network (CNN) for multivariate regression to cope with the phase aberration compensation problem automatically thus allows performing long-term monitoring of bone cells morphological response under FSS. We transformed the problem of estimating the coefficients for fitting a phase aberration map to a regression problem. The aberrated phase images are put into this model which can automatically learns the internal features of phase aberrations. Then the optimal coefficients are estimated as an output of the network. Based on these coefficients, the phase aberration map is built by the polynomial fitting, and the phase aberrations are removed by subtracting the aberration phase image with the phase map. The trainning and validation set contain thousands of phase image of cells. The mean square error (MSE) is used as the loss function. Then, the trained model was used for aberrations compensation in the FFS experiment of osteocytes. The results show that the proposed approach can predict the optimal coefficients and automatically compensating the phase aberrations without detecting background regions and knowing any physical parameters.

Cellular morphology changes and volume alterations play significant roles in many biological processes and they are mirrors of cell functions. In this paper, we propose the Digital Holographic microscope (DH) as a non-invasive imaging technique for a rapid and accurate extraction of morphological information related to cell death. In particular, we investigate the morphological variations that occur during necrosis and apoptosis. The study of necrosis is extremely important because it is often associated with unwarranted loss of cells in human pathologies such as ischemia, trauma, and some forms of neurodegeneration; therefore, a better elucidation in terms of cell morphological changes could pave the way for new treatments. Also, apoptosis is extremely important because it’s involved in cancer, both in its formation and in medical treatments. Because the inability to initiate apoptosis enhances tumour formation, current cancer treatments target this pathway. Within this framework, we have developed a transmission off-axis DH apparatus integrated with a micro incubator for investigation of living cells in a temperature and CO2 controlled environment. We employ DH to analyse the necrosis cell death induced by laser light (wavelength 473 nm, light power 4 mW). We have chosen as cellular model NIH 3T3 mouse embryonic fibroblasts because their adhesive features such as morphological changes, and the time needed to adhere and spread have been well characterized in the literature. We have monitored cell volume changes and morphological alterations in real time in order to study the necrosis process accurately and quantitatively. Cell volume changes were evaluated from the measured phase changes of light transmitted through cells. Our digital holographic experiments showed that after exposure of cells to laser light for 90-120 min., they swell and then take on a balloon-like shape until the plasma membrane ruptures and finally the cell volume decreases. Furthermore, we present a preliminary study on the variation of morphological parameters in case of cell apoptosis induced by exposure to 10 μM cadmium chloride. We employ the same cell line, monitoring the process for 18 hours. In the vast group of environmental pollutants, the toxic heavy metal cadmium is considered a likely candidate as a causative agent of several types of cancers. Widely distributed and used in industry, and with a broad range of target organs and a long half-life (10-30 years) in the human body, this element has been long known for its multiple adverse effects on human health, through occupational or environmental exposure. In apoptosis, we measure cell volume decrease and cell shrinking. Both data of apoptosis and necrosis were analysed by means of a Sigmoidal Statistical Distribution function, which allows several quantitative data to be established, such as swelling and cell death time, flux of intracellular material from inside to outside the cell, initial and final volume versus time. In addition, we can quantitatively study the cytoplasmatic granularity that occurs during necrosis. As a future application, DH could be employed as a non-invasive and label-free method to distinguish between apoptosis and necrosis in terms of morphological parameters.

A method for 3D tracking has been developed exploiting Digital Holographic Microscopy (DHM) features. In the framework of self-consistent platform for manipulation and measurement of biological specimen we use DHM for quantitative and completely label free analysis of specimen with low amplitude contrast. Tracking capability extend the potentiality of DHM allowing to monitor the motion of appropriate probes and correlate it with sample properties. Complete 3D tracking has been obtained for the probes avoiding the issue of amplitude refocusing in traditional tracking processing. Our technique belongs to the video tracking methods that, conversely from Quadrant Photo-Diode method, opens the possibility to track multiples probes. All the common used video tracking algorithms are based on the numerical analysis of amplitude images in the focus plane and the shift of the maxima in the image plane are measured after the application of an appropriate threshold. Our approach for video tracking uses different theoretical basis. A set of interferograms is recorded and the complex wavefields are managed numerically to obtain three dimensional displacements of the probes. The procedure works properly on an higher number of probes and independently from their size. This method overcomes the traditional video tracking issues as the inability to measure the axial movement and the choice of suitable threshold mask. The novel configuration allows 3D tracking of micro-particles and simultaneously can furnish Quantitative Phase-contrast maps of tracked micro-objects by interference microscopy, without changing the configuration. In this paper, we show a new concept for a compact interferometric microscope that can ensure the multifunctionality, accomplishing accurate 3D tracking and quantitative phase-contrast analysis. Experimental results are presented and discussed for in vitro cells. Through a very simple and compact optical arrangement we show how two different functionalities can be accomplished by the same optical setup, i.e. 3D tracking of micro-object and quantitative phase contrast imaging.

A compact twin-beam interferometer that can be adopted as a flexible diagnostic tool in microfluidic platforms is presented. The devise has two functionalities, as explained in the follow, and can be easily integrated in microfluidic chip. The configuration allows 3D tracking of micro-particles and, at same time, furnishes Quantitative Phase-Contrast maps of tracked micro-objects by interference microscopy. Experimental demonstration of its effectiveness and compatibility with biological field is given on for in vitro cells in microfluidic environment. Nowadays, several microfluidic configuration exist and many of them are commercially available, their development is due to the possibility for manipulating droplets, handling micro and nano-objects, visualize and quantify processes occurring in small volumes and, clearly, for direct applications on lab-on-a chip devices. In microfluidic research field, optical/photonics approaches are the more suitable ones because they have various advantages as to be non-contact, full-field, non-invasive and can be packaged thanks to the development of integrable optics. Moreover, phase contrast approaches, adapted to a lab-on-a-chip configurations, give the possibility to get quantitative information with remarkable lateral and vertical resolution directly in situ without the need to dye and/or kill cells. Furthermore, numerical techniques for tracking of micro-objects needs to be developed for measuring velocity fields, trajectories patterns, motility of cancer cell and so on. Here, we present a compact holographic microscope that can ensure, by the same configuration and simultaneously, accurate 3D tracking and quantitative phase-contrast analysis. The system, simple and solid, is based on twin laser beams coming from a single laser source. Through a easy conceptual design, we show how these two different functionalities can be accomplished by the same optical setup. The working principle, the optical setup and the mathematical modeling for 3D tracking is described. Finally, the experimental proof is presented and discussed for in vitro cells in microfluidic chamber.

Digital Holography in microscope configuration thanks to the numerical reconstruction procedure is a flexible and useful tool for analysis of biological material. We present the investigation of lipid particles growth in in-vitro mouse cell using a Digital Holographic Microscopy (DHM) employed in combination with Lateral Shear Interferometry (LSI). The optical setup is based on a Mach-Zehnder interferometer in transmission geometry. The sample cell is placed in one interferometer arm while the other one is used as a reference beam. By means of the Rayleigh-Sommerfield integral is possible to retrieve the complex object field and then to calculate the amplitude and phase of the laser light transmitted by the sample. Traditional microscopy allows to obtain amplitude contrast image only, DH, instead, enables to calculate the phase map of the complex wave that is simply related to the optical phase difference (OPD) experienced by the light when it is transmitted through the object. In this way it is possible to obtain phase contrast image that is very useful for biological materials that often present low amplitude contrast for quantitative amplitude image. The main difficulty of this technique is to remove the optical aberrations produced by the optical setup components. Several methods have been proposed, such as subtraction of a reference phase map (without sample) or numerical multiplication of a parametric lens. We propose a fast and effective solution of this problem based on LSI. We digitally introduce a lateral shear of one pixel in x and y directions calculating the phase difference ΔØ_x,y, between the actual phase map and its sheared replica in both directions. ΔØ_x,y include a linear term due to defocus aberration and the object phase difference. The linear term can be easily eliminated and sample phase map retrieved by numerical integration. This technique allows to obtain the correct phase contrast image removing optical aberration, avoiding unwrapping problems.
