Abstract: A syringe apparatus is provided for stirring and delivering single or multi-component compositions. The syringe apparatus comprises a syringe barrel, a plunger, a stirring paddle, and a connecting member. The plunger partially disposed within the syringe barrel is movable along an axial direction of the syringe barrel. The stirring paddle disposed within the syringe barrel has one end passing through the plunger and slidably disposed within the plunger. The syringe apparatus of the disclosure can stir the components and deliver the mixture safely for maintaining a good hygiene condition during the therapeutic process.

Abstract: A waterborne polyurethane complex and composition comprise a waterborne polyurethane layer being attached to a functional adhesive layer. The waterborne polyurethane layer contains a catalyst with content less than 0.001 wt %, and the catalyst is organic zinc or organic bismuth. The waterborne polyurethane complex is biocompatible and non-irritable, and is adapted for cell therapy or biomedical application.

Abstract: The NH3 plasma treatment by remote plasma is firstly proposed to replace the covalent bonding process during surface modification procedure that for amine bond generation.

Abstract: A method of forming cell spheroids cultured in a serum-free manner on nanoscale coatings of hyaluronic acid with high molecular weight is disclosed. Corneal stromal cells are cultured on the hyaluronic acid coatings with nanotopography in the serum-free manner. Experimental results show that the cells cultured on the hyaluronic acid coatings (1.1-1.7 nm) increase cell-cell interaction, and when the cells form three-dimensional spheroids, they have higher biological synthetic capabilities and can secret more extracellular matrix, which has potential applications in corneal stromal tissue reconstruction.
