IHydroxyapatite Yenziwe: Ukuqulunqwa kunye nabavelisi abaPhezulu 

I-Hydroxyapatite yenziwe ngokuyinhloko nge-calcium kunye ne-phosphate ions, ehlelwe kwi-crystalline structure kunye ne-chemical formula Ca₁₀(PO₄)₆(OH)₂. Lenza malunga ne-70% yethambo lomntu kunye ne-90% yezinyo le-enamel yezinyo ngokobunzima. Kwizicelo zoshishino kunye nezonyango, i-high-purity hydroxyapatite (HAp) idityaniswe ngokugqithiswa kweekhemikhali ezimanzi, iinkqubo ze-sol-gel, okanye iindlela ze-hydrothermal zokuqinisekisa ukuba i-biocompatibility, i-osteoconductivity, kunye nokunyaniseka kwesakhiwo sokusetyenziswa kwi-grafts yamathambo, ukufakelwa kwamazinyo, kunye ne-cosmetic formulations ephezulu.

Yenziwe ngantoni iHydroxyapatite? Ukubunjwa kwemichiza kunye noLwakhiwo

Ukuqonda ukuba yenziwe ngantoni i-hydroxyapatite kufuna ukujonga ngaphaya kwezinto zayo ezisisiseko. Ngelixa iibhloko zokwakha ezisisiseko ziyi-calcium kunye ne-phosphorus, ukusebenza kwe-HAp kwi-biomedical kunye ne-cosmetic applications kuxhomekeke kakhulu kwi-crystallinity yayo, i-stoichiometry, kunye ne-ionic substitutions.

Amacandelo angundoqo

Kwinqanaba layo elisisiseko, i-stoichiometric hydroxyapatite iqukethe:

• Ikhalsiyam (Ca): Ibonelela ngozinzo lwesakhiwo kwaye idlala indima ebalulekileyo ekubonakalisweni kwebhayoloji kunye nokuchithwa kwamathambo.
• Iphosphate (PO₄): Yenza iiyunithi ze-tetrahedral ezidibanisa i-calcium ions, idala isakhiwo esiqinileyo se-lattice.
• Iqela leHydroxyl (OH): Ifumaneka kwiitshaneli zekristale, la maqela anempembelelo kwintlawulo yomhlaba kunye nokusebenza kwakhona.

Umlinganiselo ofanelekileyo we-Ca/P we-molar ye-hydroxyapatite ecocekileyo yi 1.67. Ukuphambuka kulo mlinganiso kunokubangela i-apatites engeyiyo ye-stoichiometric, enokuthi ibonise amazinga ahlukeneyo okuchithwa kunye neempendulo zebhayoloji. Kubavelisi kunye nabaqulunqi, ukugcina lo mlinganiselo uchanekileyo kubalulekile ekuqinisekiseni ukusebenza okuqikelelweyo kwi-vivo okanye kwi-topical applications.

Ulwakhiwo lweCrystalline kunye neePropati

I-Hydroxyapatite yeyenkqubo ye-crystal ene-hexagonal. Eli lungiselelo elithile livumela ukuba lilinganise isigaba samaminerali sethambo lendalo ngokusondeleyo. Iqondo lekristale-indlela eyalelwe ngayo i-crystal lattice-ichaphazela kakhulu iimpawu zayo:

• Ubukhazikhazi obuphezulu: Iziphumo kumandla omatshini amakhulu kunye namazinga okuthotywa kancinci, alungele ukufakwa kwamathambo okuthwala umthwalo.
