Hygroscopic, crosslinking coatings and bioadhesives
According to the present disclosure, a bioadhesive formulation is provided. The bioadhesive formulation comprises a polycaprolactone dendrimer having a dendrimer core and a plurality of polycaprolactone chains extending from the dendrimer core, wherein at least one of the polycaprolactone chains has an end which is covalently attached with a diazirine, and wherein the diazirine converts to a carbene or a diazoalkyl when a stimulant is applied to the bioadhesive formulation. Methods of forming the bioadhesive formulation are also provided. The bioadhesive could be used in (i) the prevention of thrombosis from tissue fixation and/or (ii) the relief of discomfort and/or pain during and/or after surgery. Preferably, the bioadhesive formulation further comprises a hygroscopic additive, an antithrombotic agent, and/or an anaesthetic agent.

Method for preparing absorbable haemostatic composition for body and haemostatic composition prepared thereby
The present disclosure relates to a method for preparing an absorbable haemostatic composition for the body and the haemostatic composition prepared thereby, and the present disclosure is for providing a method for preparing an absorbable haemostatic composition for the body and the haemostatic composition prepared thereby, wherein the haemostatic composition can be used directly on the wound site when bleeding occurs in the surgical area such as surgical operation, trauma, etc. so that hemostasis can be effectively performed, the haemostatic composition can perform wound sealing, tissue repairing promotion, wound surface tissue protection, infection prevention, etc., the haemostatic composition is contained in haemostatic products such as gauze (cotton yarn), sponge, etc. to accelerate the hemostasis speed of the bleeding site and enable rapid hemostasis to be able to shorten the hemostasis time at the same time.
METHOD FOR PREPARING CERAMIC MATERIALS
Provided herein is a method of preparing a ceramic material, the method including: providing a ceramic gel including a plurality of metal salts and compressing the ceramic gel thereby inducing stress-induced mineralization of the ceramic gel and formation of the ceramic material, wherein the ceramic gel exists in isolated form.
