Mechanism and functional efficacy of hydroxyapatite nanopowder

As a drug carrier:
Hydroxyapatite nanopowder have many advantages such as good biocompatibility, low pH sensitivity, controllable structure, large drug loading and high encapsulation efficiency, and are widely used as drug carriers. At the same time, the synthetic hydroxyapatite is surface-modified to load a specific drug, and can also solve the problem of release of drug release.
Hydroxyapatite nanopowder
Hydroxyapatite is the main component of human teeth and osteophytes:

The hydroxyapatite nanopowderl is similar to the human bone structure and has similar biocompatibility, and is widely used in bone defect repair. Nano-sized fibrous hydroxyapatite or porous network hydroxyapatite prepared by controlled conditions, the surface of the material is favorable for the attachment of osteoblasts, and the pore structure is beneficial to the growth and differentiation of osteoblasts, and can promote bone repair and growth. At the same time, in combination with other antibacterial means, it will be a dual-effect material with bone growth and anti-infection, which is a research hotspot.

As an anti-tumor "new weapon":

Studies have shown that nano-hydroxyapatite exhibits excellent anti-tumor activity, and its anti-tumor mechanism is a mitochondria-dependent apoptotic pathway and a negative regulation of the PIK3/AKT pathway for the development of advanced biocompatible nanocrystals for nanomedicine. Has a high value.

Nano-hydroxyapatite performance advantage

1. Good biocompatibility and stability, large specific surface area, biodegradable, inherent antibacterial activity,
Rich in modification sites
2. Low cost and simple preparation process
Application prospects
Simple hydroxyapatite materials have not been able to meet today's needs, more are seeking
The combination of hydroxyapatite and other materials, which plays a role in the excellent properties of hydroxyapatite
Based on the development of multi-functional composite materials:
Hydroxyapatite is combined with Au and Ag to obtain a composite material having an antibacterial effect;
Hydroxyapatite combined with carbon dots,
Anti-tumor composite materials utilizing carbon dot radiation properties;
Magnetic iron oxide combined with hydroxyapatite,
A targeted anti-tumor drug carrier or the like is obtained.

EPDM rubber parts are generally cheaper than silicone parts

EPDM is ethylene, propylene, mix a small amount of the conjugate olefin copolymer, is one of the types of ethylene propylene rubber, expressed in EPDM, because its main chain is made up of chemical stability of saturated hydrocarbon, and only in the side chain containing unsaturated double bond, so the ozone resistance, heat resistance, excellent weather resistance and aging resistance, can be widely used in auto parts, building waterproof materials, wire and cable sheath, heat-resistant rubber hose, adhesive tape, automotive seals, and other fields. With the recovery of Chinese economy, automobile, construction and other pillar industries have entered a period of rapid development, which has significantly boosted the market demand for EPDM.In 2012, the apparent consumption of EPDM in China reached 227,500 tons. The import dependence of the industry is still very high, and it is still growing in recent years.In the future, the rubber market of EPDM will enter a demand peak. In 2015, t...
