Latest Patents

One of Jeffrey Chen's latest patents is titled "Ultrathin interfacial layer on a hydrogel to direct its surface properties and cell adhesion." This patent discloses a method for coating and patterning hydrogels to modify their surface properties. The method utilizes the water content of the hydrogel and the hydrophobicity of the reaction solvent to create a thin oxide adhesion layer on the hydrogel surface. This innovation allows for the rapid transformation of hydrophilic, cell non-adhesive hydrogels into either highly hydrophobic or cell-adhesive variants through reactions with specific chemical agents.

Another notable patent is focused on "Methods of protecting concrete from freeze damage." This invention provides a method for protecting a cementitious mixture from freeze damage by incorporating an entrainment air composition into the mixture. This process forms air voids in the concrete and adds an effective agent for nucleating ice within those voids. The result is a concrete structure that can withstand freeze-thaw cycles more effectively.
