Optical microscopy is an indispensable diagnostic tool in modern healthcare. As a prime
example, pathologists rely exclusively on light microscopy to investigate tissue morphology …

For quantitative phase imaging (QPI) based on transport-of-intensity equation (TIE), partially
coherent illumination provides speckle-free imaging, compatibility with brightfield …

Population heterogeneity among a microbial culture can occur in various stages of a
bioprocess. When a nutrient-limited fed-batch process is applied in the large scale, gradient …

Cell refractive index, an intrinsic optical parameter, is closely correlated with the intracellular
mass and concentration. By combining optical phase-shifting interferometry (PSI) and atomic …

Background Red blood cells collected in citrate-phosphate-dextrose can be stored for up to
42 days at 4 C in saline-adenine-glucose-mannitol additive solution. During this controlled …

We introduce inline digital holographic microscopy (in-line DHM) as a label-free technique
for detecting tumor cells in blood. The optimized DHM platform fingerprints every cell flowing …

We propose a compact and easy-to-align lateral shearing common-path digital holographic
microscopy, which is based on a slightly trapezoid Sagnac interferometer to create two …

Living cells are composed of active materials, in which forces are generated by the energy
derived from metabolism. Forces and structures self-organize to shape the cell and drive its …

We report on a compact optrode, ie a MEMS-based, invasive, bidirectional neural interface
allowing to control neural activity using light while neural signals are recorded nearby. The …

The exposure to visible light has been shown to exert various biological effects, such as
erythema and retinal degeneration. However, the phototoxicity mechanisms in living cells …
