Title: Innovations of Tuo Jin in Microneedle Technology
Introduction
Tuo Jin is a prominent inventor based in Shanghai, China, known for his significant contributions to the field of microneedle technology. With a total of 10 patents to his name, he has developed innovative methods that enhance the efficiency and effectiveness of microneedle applications.
Latest Patents
One of Tuo Jin's latest patents is a method to print microneedle patches rapidly. This invention teaches a method to achieve rapid 3D printing of microneedle patches. The 3D printing method comprises a printing nozzle with multiple micro-holes and a cold plate/platform on which the microneedle-supporting sheet is placed. The solution or aqueous solution of microneedle-forming materials is printed onto the cold microneedle-supporting sheet with a programmed rate of injection from the nozzle and the velocity of the nozzle lifting. The relationship between the injection rate and the lifting velocity determines the shape of the microneedle tips. The freshly printed microneedles on the cold sheet are dried in two ways: drying at a temperature close to the ice point of water or drying after a freeze-thaw treatment of the microneedles. Another notable patent is the process for producing polymeric microspheres. This disclosure involves a microsphere-producing process that integrates three unit operations: microspheres formation, microsphere quality control, and post-formation microsphere treatment. The first unit operation includes essential functions such as forcing the particle-forming materials to pass through a porous membrane to form embryonic microspheres, detaching the embryonic microspheres from the porous membrane, solidifying the embryonic microspheres, and collecting the solidified microspheres. The quality control unit operation consists of the discrimination and ejection of oversized microspheres. The post-treatment unit operation integrates functions for smoothing the microsphere surfaces and reducing organic solvents trapped inside the microsphere matrix.
