Simulating nature in sperm selection for assisted reproduction
ETY Leung, CL Lee, X Tian, KKW Lam, RHW Li… - Nature Reviews …, 2022 - nature.com
Sperm selection in the female reproductive tract (FRT) is sophisticated. Only about 1,000
sperm out of millions in an ejaculate reach the fallopian tube and thus have a chance of …

Multiscale label-free volumetric holographic histopathology of thick-tissue slides with subcellular resolution
Histopathology relies upon the staining and sectioning of biological tissues, which can be
laborious and may cause artifacts and distort tissues. We develop label-free volumetric …
