1. Introduction to bacterial cellulose

Bacterial Cellulose ( BC ) is a natural polymer material synthesized by microorganisms with nanoscale fiber diameter ( 20–100 nm ) and a three- dimensional network structure. Compared with traditional plant cellulose, BC has higher purity and better crystallinity, and has excellent mechanical properties and biocompatibility, so it has great potential in the field of medical and health.

2. Key performance

High biocompatibility : does not trigger immune rejection in the body;

Excellent water absorption : It can absorb hundreds of times its own weight and keep the wound moist;

Good mechanical properties : flexible and stable, suitable for repair of human soft tissue;

Nanopore structure : conducive to nutrient exchange and drug loading;

Large functional space : antibacterial, conductive or sustained release effects can be achieved through modification.

3. Application in the field of medical and health

1. Trauma dressings and artificial skin

BC is widely used for the repair of wounds such as burns and chronic ulcers due to its high water absorption and good breathability. Research shows that BC dressings can speed up healing and reduce scar production. In recent years, Nanjing Tianlu Nano Technology Co., Ltd. has continued to develop in this direction. produced through process optimization The BC dressing has better moisture retention and oxygen permeability than traditional materials, and is more in line with clinical needs.

2. Tissue Engineering and Regenerative Medicine

BC 's three-dimensional nanonetwork provides the ideal ' growth scaffold ' for cells . in studies such as bone repair, cartilage replacement and vascular regeneration . BC has shown good prospects developed by Nanjing Tianlu Nano Technology Co., Ltd. and the research institute The BC composite scaffold has achieved faster bone integration in animal experiments, laying the foundation for future clinical applications.

3. Drug delivery and sustained release system

By regulating the pore structure of BC , sustained release and directed delivery of drugs can be achieved. For example, BC -based transdermal patches and controlled release membranes can improve drug utilization and reduce side effects. Nanjing Tianlu Nano Technology Co., Ltd. is exploring the combination of BC with antibacterial ingredients for a new generation of smart drug delivery systems.

4. Artificial organs and biomedical materials

In the fields of artificial blood vessels, artificial cornea and cardiac repair, BC has gradually been verified due to its high mechanical strength and good oxygen permeability. The company's team is expanding the application of BC materials in medical and repair membranes, with the goal of developing next-generation biological alternative materials that are available clinically.
