Application

Lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP) is a water soluble, cytocompatible, Type I photoinitiator for use in the polymerization of hydrogels or other polymeric materials. This photoinitator is preferred over Irgacure 2959 for biological applications due to its increased water solubility, increased polymerization rates with 365 nm light, and absorbance at 400 nm allowing for polymerization with visible light. The improved polymerization kinetics enable cell encapsualation at reduced initiator concentration and longer wavelength light, which has been shown to reduce initiator toxicity and increase cell viability.

Inspired by the interesting natural antimicrobial properties of honey, biohybrid composite materials containing a low-fouling polymer hydrogel network and an encapsulated antimicrobial peroxide-producing enzyme have been developed. These synergistically combine both passive and active mechanisms for reducing microbial bacterial colonization.

Despite significant advances in osteochondral tissue engineering, it remains challenging to successfully reconstruct native-like complex tissues organized in three-dimension with spatially varying compositional, structural and functional properties. In this contribution, inspired by the gradients in extracellular matrix (ECM) composition and
