He aha ka PDLLA Poly(DL-lactide) CAS 51056-13-9 ?

ʻO PDLLA kahi polymer amorphous me kahi mahana hoʻololi aniani o 50-60 ℃ a me kahi ākea viscosity o 0.2-7.0dl / g. Ua ʻae ʻia ka mea e ka FDA a hiki ke hoʻohana ʻia ma ke ʻano he adjuvant no ka lāʻau lapaʻau anti-adhesive mucosa, microcapsules, microspheres a me nā implants no ka hoʻokuʻu mau ʻana, a hiki ke hoʻohana ʻia e like me nā scaffolds porous no ka moʻomeheu cell engineering a me ka hoʻoponopono ʻana i ka iwi a i ʻole nā mea hoʻoponopono kiko, e like me nā sutures surgical, implants, artificial blood vessel, retimic artificial.

1. Medical cosmetology‌: Hoʻohana nui ʻia ʻo PDLLA ma ke ʻano he mea hoʻopiha maka ma ke kahua o ka cosmetology lapaʻau ma muli o kona biocompatibility maikaʻi loa a me ka degradability. Hiki iā ia ke hoʻoulu i ka hana ʻana o ka ʻili collagen, ma laila e hoʻomaikaʻi ai i ka ʻili o ka ʻili, nā wrinkles a me ke kaumaha.

2. Nā mea lapaʻau‌: Hoʻohana nui ʻia ʻo PDLLA ma ke kahua o nā lāʻau lapaʻau, e like me nā uhi i hoʻopiha ʻia i ka lāʻau no nā stents coronary degradable, sutures surgical, hemostatic clips, etc.

3. ʻEnekinia Tissue‌: He mau noi koʻikoʻi ko PDLLA ma ke kahua o ka ʻenekinia kiko, e like me ka hoʻoponopono iwi a me nā mea hoʻoponopono iwi, nā scaffolds ʻenekinia kiko, a me nā mea ʻē aʻe.

4. Hoʻokuʻu ʻia ka lāʻau: Hiki ke hoʻohana ʻia ʻo PDLLA no ka hoʻokuʻu ʻana i ka lāʻau lapaʻau a me ka hoʻokuʻu hoʻokuʻu hoʻomau. Ma ka hui pū ʻana me nā lāʻau lapaʻau e hana i nā ʻano hana e like me microspheres a i ʻole microcapsules, hiki ke hoʻokō ʻia ka hoʻokuʻu lohi a me ka hana hoʻomau o nā lāʻau lapaʻau, e hoʻomaikaʻi ai i ka pono a me ka palekana o nā lāʻau lapaʻau.

5. ʻO ka hana hoʻohaʻahaʻa ʻana o PDLLA‌: Hoʻohaʻahaʻa mālie ʻo PDLLA, hiki iā ia ke hāʻawi i nā hopena therapeutic lōʻihi loa i nā noi lapaʻau. ʻO kāna huahana degradation he lactic acid, ka mea i hoʻololi ʻia i carbon dioxide a me ka wai, a ʻaʻohe mea ʻawaʻawa a maikaʻi ʻole i ke kino kanaka‌
