LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening
Advanced Science, EarlyView.LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

Prepolymerization Enables On‐Demand Viscosity Tuning for Xolography of Soft Hydrogels
Advanced Science, EarlyView.A facile in situ prepolymerization strategy enables on‐demand viscosity tuning across three orders of magnitude without external thickeners, transforming low‐viscosity resins into printable formulations for Xolography. The approach suppresses sedimentation, lowers curing dose, enables high‐fidelity support‐free fabrication, and produces advanced ...
