Latest Patents

Weng's latest patents include innovative microfluidic systems designed to denude mammalian oocytes. These systems are configured to process liquid samples containing cumulus-oocyte complexes (COCs) in an automated and continuous manner. The technology aims to produce oocytes that are separate from surrounding cumulus cells. The systems feature a substrate and a channel with multiple sub-channels, each equipped with inlets, outlets, and stages arranged in series. Notably, some stages include constriction units with jagged internal surfaces that facilitate the removal of cumulus cells from COCs.

Another significant patent involves high subzero cryopreservation methods. This innovation is based on the discovery that endothelial cells exhibit improved attachment and viability after preservation when exposed to heterogeneous extracellular ice. By uniformly nucleating ice across the microvasculature using ice nucleating agents, the risk of intracellular ice formation is significantly reduced, enhancing the preservation of biological samples, organs, and organisms.
