Label-free Monitoring of Nucleoid Dynamics of Bacteria for Drug Screening Using Holography
Gauresh Raj Jassal, Jiaqi Li, Lei Feng +3
We introduce holographic microscopy (HM) as a compact, low-cost, label-free, non-specific alternative to fluorescence microscopy (FM) for quantifying bacterial physiological respon…
HoloCMA: A Holographic Eye on Coarse-Mode Aerosols
Nikil Krishnakumar, Ryne A. Juidici, Nicholas Bravo-Frank +8
Coarse-mode aerosols (CMAs), including pollen, spores, and dust, remain difficult to characterize in situ because conventional instruments rarely resolve particle geometry and numb…
Realtime Particulate Matter and Bacteria Analysis of Peritoneal Dialysis Fluid using Digital Inline Holography
Nicholas Bravo-Frank, Nicolas Mesyngier, Lei Feng +1
We developed a digital inline holography (DIH) system integrated with deep learning algorithms for real-time detection of particulate matter (PM) and bacterial contamination in per…
Holographic Air-quality Monitor (HAM)
Nicholas Bravo-Frank, Lei Feng, Jiarong Hong
We introduce the holographic air-quality monitor (HAM) system, uniquely tailored for monitoring large particulate matter (PM) over 10 um in diameter, i.e., particles critical for d…
