Abstract: The present invention relates to an anti-adhesion polymer composition. The anti-adhesion polymer composition according to the present invention has excellent adhesion performance so as to be continuously attached successfully to a wound site generated during surgery while also effectively exhibiting an anti-adhesion function, has antibacterial and hemostatic properties, and has excellent formulation stability.

Abstract: The present invention relates to a small urea sensor module, configured such that a urease-immobilized insoluble porous support, in which urease is immobilized on a porous support made of a natural polymer such as silk fibroin, etc. or a synthetic polymer, is mounted in a fluidic chamber and also such that the electrode surface of a three-electrode strip is exposed to the bottom surface of the chamber. This urea sensor is essential for the evaluation of the regenerated solution from a portable peritoneal dialysis fluid regeneration system and has advantages such as portability, reproducibility, mass productivity and simplicity, which will greatly contribute to disease management of patients with chronic renal disease.

Abstract: There is provided a method of preparing a fluorescent silk fibroin solution, which includes a) obtaining scoured fluorescent silk fibroin by adding transgenic fluorescent silkworm cocoons to an aqueous solution including a scouring agent, heating the transgenic fluorescent silkworm cocoons at 40 to 60° C. for 8 to 24 hours and washing the transgenic fluorescent silkworm cocoons with distilled water, b) dissolving the scoured fluorescent silk fibroin at 40 to 60° C. for 1 to 5 hours in a solvent in which 15 mg to 1.5 g of dithiothreitol (DTT) is mixed per 100 mL of 9 to 9.6 M LiBr, and c) dialyzing the dissolved fluorescent silk fibroin in single distilled water for 48 to 96 hours. The scouring agent includes an alcalase and sodium hydrogen carbonate (NaHCO3). The conventional methods of preparing a silk fibroin solution from fluorescent silkworm cocoons have drawbacks in that silk fibroin is not dissolved at a low temperature and fluorescence is lost.
