eSUNMED Obtains Patent Authorization for “A Medical Biodegradable Microsphere and Its Preparation Process”!

Post time: Jun-07-2024

On May 31, 2024, the “A Medical Biodegradable Microsphere and Its Preparation Process”, independently developed by Shenzhen Esun Industrial Co., Ltd. and its subsidiary eSUNMed Biotechnology (Shenzhen)Co.,Ltd., was officially approved by the National Intellectual Property Administration and obtained national invention patent authorization. The medical biodegradable microspheres developed based on this invention possess excellent biodegradability.

Currently, eSUNMED has achieved a full-process technical layout for medical implant biomaterials. The company has related patent technologies in aspects such as monomer synthesis and purification, polymer synthesis, material processing, and application. This includes patents for monomer purification, medical non-toxic high-efficiency catalysts, preparation of microspheres, polylactic acid implant films, and more.

Polylactic acid (PLA) is one of the common materials that are fully biodegradable and environmentally friendly. Polylactic acid (PLA) microspheres have good biocompatibility and biodegradability.

In practical applications, the advantages of medical biodegradable microspheres are quite evident. Taking their use in the field of medical aesthetics as an example, PLA microspheres can be used as injectable fillers to increase skin fullness, improve wrinkles, and alleviate skin laxity. Due to the superior biodegradability of PLA microsphere fillers, they can gradually decompose and be metabolized, not causing lasting effects on the skin. Moreover, through various modification techniques, different properties can be imparted to PLA microsphere fillers, such as varying degradation periods.

Additionally, biodegradable microspheres are also quite popular in drug delivery and tissue engineering applications. For example, degradable drug-loaded microspheres gradually decompose after entering the body, allowing the drug to be released slowly at a certain rate. This maintains the concentration of the drug in the blood at the site of the lesion, thereby extending the drug’s half-life and achieving long-term sustained release. For patients, this can significantly reduce the frequency of administration and improve compliance.

Biodegradable microspheres are a global industrial hotspot, offering significant advantages in clinical and various related fields. The future development prospects are very broad. eSUNMED welcomes research institutions or enterprises with needs to contact us for product customization or new application development!
