PDLLA Poly (DL-lactide) CAS 51056-13-9 yog dab tsi?

PDLLA yog ib qho amorphous polymer nrog iav hloov kub ntawm 50-60 ℃ thiab viscosity ntau ntawm 0.2-7.0dl / g. Cov ntaub ntawv tau txais kev pom zoo los ntawm FDA thiab tuaj yeem siv los ua cov khoom siv kho mob rau kev phais mob los tiv thaiv cov nplaum mucosa, microcapsules, microspheres thiab cog rau kev tso tawm, thiab tseem tuaj yeem siv los ua ntxeem tau rau cov ntaub so ntswg engineering cell kab lis kev cai thiab pob txha kho lossis cov ntaub so ntswg kho, xws li phais sutures, tin implants, artificial hlab ntsha, thiab cov ntaub so ntswg.

Daim ntawv thov

1. Kev kho mob cosmetology : PDLLA yog dav siv los ua lub ntsej muag muab tub lim hauv kev kho mob cosmetology vim nws zoo heev biocompatibility thiab degradability. Nws tuaj yeem txhawb kev tsim ntawm daim tawv nqaij collagen, yog li txhim kho daim tawv nqaij sagging, wrinkles thiab kev nyuaj siab.

2. Cov cuab yeej kho mob: PDLLA kuj tau siv dav hauv kev kho mob, xws li cov tshuaj-loaded coatings rau degradable coronary stents, phais sutures, hemostatic clips, thiab lwm yam.

3. Cov ntaub so ntswg engineering : PDLLA kuj tseem muaj cov ntawv thov tseem ceeb hauv kev ua haujlwm ntawm cov ntaub so ntswg, xws li pob txha kho thiab kho pob txha cov ntaub ntawv, cov ntaub so ntswg engineering scaffolds, thiab lwm yam.

4. Tshuaj tswj kev tso tawm: PDLLA kuj tseem siv tau rau kev tso tshuaj yeeb tshuaj thiab ntim ntim tso tawm. Los ntawm kev sib xyaw nrog cov tshuaj los ua cov ntaub ntawv ntau npaum li microspheres lossis microcapsules, qhov kev tso tawm qeeb thiab kev ua haujlwm ntawm cov tshuaj tuaj yeem ua tiav, yog li txhim kho cov txiaj ntsig thiab kev nyab xeeb ntawm cov tshuaj.

5. Kev ua haujlwm tsis zoo ntawm PDLLA : PDLLA degrades kuj qeeb, uas ua rau nws muab kev kho mob ntev dua hauv kev siv tshuaj kho mob. Nws cov khoom degradation yog lactic acid, uas thaum kawg metabolized rau hauv carbon dioxide thiab dej, thiab yog non-toxic thiab harmless rau tib neeg lub cev.
