Label-free spatio-temporal monitoring of cytosolic mass, osmolarity, and volume in living cells
Label-free, spatio-temporal imaging of cellular physiological responses is challenging. Here the authors combine digital holographic microscopy with a millifluidic chip and mathematical modelling to quantify cell volume, mass and cell uptake under ...

P-TDHM: Open-source portable telecentric digital holographic microscope
We present the design of a low-cost, portable telecentric digital holographic microscope (P-TDHM) that utilizes off-the-shelf components. We describe the system’s hardware and software elements and evaluate its performance by imaging samples ranging from
