Protein Surface Polymer Ultrasonic Stent Coating
Description:
Ultrasonic spraying has high controllability and can provide very high transfer efficiency for precise thin films of solutions or suspensions such as biopolymers, proteins, EDTA, heparin, amino acids, enzymes, plasma, and preservatives. Therefore, the medical industry is one of the earliest fields in which ultrasonic spraying entered. In the field of biomedicine, ultrasonic spraying is mainly used in drug preparation and controlled release systems, drug delivery, medical device coatings, medical equipment coatings, bioprinting, etc. It can not only help improve drug controlled release effects, enhance the performance and functionality of medical devices, but also achieve high-quality coating preparation, and has broad application potential in the field of pharmaceutical biomedicine.
Protein surface polymer ultrasonic scaffold coating is a challenging spray application. Strict requirements have been put forward for the manufacturing processes used to produce them. Ultrasonic spraying is very suitable for this application because it utilizes piezoelectric ceramics to generate vibrations ranging from tens to hundreds of kilohertz, forming particles of tens or even hundreds of micrometers without the need for high-pressure air pressure. It can accurately and efficiently spray the bracket, and the production environment is easy to control without the introduction of pollutants.
