Biomedical Polymer Micropowder

Short Description:

Micropowder is a small spherical entity formed by dispersing or adsorbing drugs in a polymer matrix. The particle size of the aggregated biological micropowders can be selected from 3 to 100 μm, and the conventional molecular weight is within 100,000. The processing technology of polybiotic micropowders can serve medical beauty, drug sustained release, targeted drug delivery, cosmetics and other medical related fields.

  • Micropowder processing services: PLA Micropowders, PCL Micropowders and PLGA Micropowders, etc.
  • Micropowder particle size: 3-100μm optional
  • Conventional molecular weight: within 100,000, other molecular weights and particle sizes can be customized
  • Application fields: medical beauty, drug sustained release, targeted drug delivery, cosmetics and other medical related fields

Product Detail

Jusing can provide biodegradable medical micropowder processing services according to user needs, such as PLA micropowder, PCL micropowder and PLGA micropowder. And particle size can be customized by consultation.

1. PLA Micropowder

Polylactic acid micropowder refers to the existence of polylactic acid in the form of micropowder. It is generally used as a drug carrier. Due to its good biocompatibility and biodegradability, polylactic acid (PLA) has become the most popular in the current biomedical field because its degradation products can participate in the metabolism of the human body and its properties can be adjusted in a wide range by copolymerization with other monomers. One of the most important materials.

Histological studies have shown that PLA and its copolymers are used as controlled release carriers for some drugs with a short half-life, poor stability, easy degradation and large toxic and side effects, such as antibiotics, anticancer drugs, vaccines, hormones, family planning drugs, antipyretic and analgesic It can effectively increase the route of administration, reduce the number and amount of administration, improve the availability of drugs, and reduce the side effects of drugs on the liver and kidneys.

2. PCL Micropowder

PCL (polycaprolactone), as a biodegradable medical material with good biocompatibility, is often used in long-acting sustained-release dosage forms of drugs due to its long degradation time, and is especially suitable for the development and application of microsphere carriers. At the same time, polycaprolactone and its composites are also candidate materials for bone tissue engineering scaffolds.

3. PLGA Micropowder

PLGA is an FDA-approved polyester polymerized from two monomers, lactic acid and glycolic acid, and has been widely used in micropowder due to its good biocompatibility, biodegradability, and controllable mechanical properties preparation. The microsphere system has the advantages of protecting the drug from damage, targeting the drug to some special tissues, delaying/controlling the release of the drug, prolonging the action time of the drug, and reducing the toxicity and irritation of the drug. There are many reports on the preparation and application of various PLGA drug micropowder. Among them, PLGA micropowder is the research hotspot as the carrier of protein and enzyme drugs.
