Ucoceko oluPhezulu 45S5 uMvelisi weglasi yeBioactive kunye noMboneleli 

Ukucoceka okuphezulu kwe-45S5 yeglasi ye-Bioactive yi-biomaterial esekelwe kwi-silicate esekelwe kwi-45% ye-SiO₂, i-24.5% ye-Na₂O, i-24.5% ye-CaO, kunye ne-6% ye-P₂O₅ ngesisindo. Njengomboneleli ophambili wezinto ezikumgangatho wezonyango, sibonelela nge-45S5 umgubo kunye neegranules ezenzelwe ukuvuselelwa kwamathambo, ukusetyenziswa kwamazinyo, kunye nokhathalelo lwenxeba. Ikhonkco lethu lokubonelela liqinisekisa ulawulo olungqongqo lwe-stoichiometric, umxholo wesinyithi onzima ophantsi, kunye nokuhanjiswa kobungakanani besuntswana, ukuhlangabezana nemigangatho ye-ISO 13485 yezixhobo ezifakelwayo. Esi sixhobo sibonisa ukubunjwa kwe-hydroxyapatite ngokukhawuleza ekudibaneni nolwelo lwe-physiological, okwenza ukuba i-chemical bonding eyomeleleyo kunye nezicubu eziqinileyo kunye nezithambileyo.

Yintoni i-High Purity 45S5 Bioactive Glass?

I-45S5 Bioglass®, eyaphuhliswa ekuqaleni nguNjingalwazi uLarry Hench ngo-1969, ihlala ingumgangatho wegolide kwiiseramikhi ze-bioactive. Igama elithi "45S5" libonisa ukubunjwa kwayo: 45 wt% silica (SiO₂) kunye ne-5: i-1 ye-molar ratio ye-calcium kwi-phosphorus. Ngokungafaniyo ne-inert biomaterials ezifana ne-titanium okanye i-alumina, i-45S5 i-bioactive, oku kuthetha ukuba iqalisa impendulo ethile yebhayoloji kwi-interface, ekhokelela ekubunjweni kwebhondi phakathi kwezinto kunye nezicubu eziphilayo.

Izahluko eziphezulu zokucoceka zibalulekile kwizicelo zeklinikhi apho umkhondo wokungcola unokubangela iimpendulo ezivuthayo okanye uthintele i-osteogenesis. Iprothokholi yethu yokukhangela igxile ekupheliseni ungcoliseko lwesinyithi kunye nokuqinisekisa ukuhambelana kwe-homogeneity kwinethiwekhi yeglasi. Oku kuhambelana kubalulekile kumazinga okuthotywa okuqikelelweyo kunye neeprofayili zokukhutshwa kwe-ion, eziphembelela ngokuthe ngqo ukuziphatha kweselula kunye nokudityaniswa kwezicubu.

Ukuqulunqwa okukodwa kwe-45S5

Ukusebenza kwe-45S5 kulele ekubunjweni kwayo kwe-oxide ethile. Olu qulunqo lubeka iglasi ngaphakathi kwe "window ye-bioactive" ye-ternary diagram ye-SiO₂-Na₂O-CaO. Ukutenxa kulo mlinganiselo uchanekileyo unokunika i-bioinert yezinto eziphathekayo okanye i-resorbable ngaphandle kokukwazi ukubopha.

• I-Silica (SiO₂): Yenza umqolo wenethiwekhi yeglasi. Kwi-45%, inika uzinzo olwaneleyo ngelixa ivumela ukuchithwa ngokukhawuleza.
• I-Sodium oxide (Na₂O): Isebenza njengesilungisi senethiwekhi, ukwandisa ukunyibilika kunye nokuququzelela ukutshintshiselana kwe-ion kunye nolwelo lomzimba.

Njengebhulorho eqhutywa lulwazi phakathi kokuveliswa kwezinto ezintsha kunye nesicelo esisezantsi, iJinan Meiyi Biotechnology ihlala iphambili kolu phuhliso ukunika izisombululo zesizukulwana esilandelayo.

Doping ngee-Ions yoNyango

Abaphandi baphonononga ukutshintshwa kwezilungisi zenethiwekhi ngee-ion zonyango ezifana ne-strontium, i-magnesium, i-zinc, kunye ne-boron. Ezi glasi ze-doped zibonelela ngeziphumo zebhayoloji eziphuculweyo, ezinjengonyango oluphuculweyo lwe-osteoporosis (strontium) okanye ukwanda komsebenzi we-antibacterial (zinc/silver). Sinikezela ngokufikelela kwiinkonzo zedoping zesiko kwiiprojekthi ezikhethekileyo ze-R&D ngenethiwekhi yethu yamaqabane.

Izinto ezihlanganisiweyo

Ukuhlanganiswa kwe-45S5 kunye neepolymers zendalo ezifana ne-chitosan, i-alginate, kunye ne-collagen ifumana i-traction. Ezi ngqungquthela zilinganisa i-matrix ye-extracellular yendalo, inika i-adhesion engcono yeeseli kunye neempawu zomatshini. I-Hybrid scaffolds ibonisa isithembiso sokulungiswa kwe-cartilage kunye nobunjineli bezicubu ezithambileyo, iindawo ezinomdla ngokukodwa kwishishini le-aesthetics yonyango.

Ukufakelwa kwe-Smart

Ukudibanisa i-45S5 kunye neenzwa okanye izinto eziqhubayo zenza izifakelo ezihlakaniphile ezikwazi ukubeka iliso kwinkqubela phambili yokuphilisa. Iglasi ye-bioactive ibonelela ngokusingqongileyo okuvuselelayo, ngelixa ii-sensors ezifakwe ngaphakathi zilandelela iiparamitha ezifana ne-pH, ubushushu, kunye noxinzelelo, ukubonelela ngedatha yexesha langempela kwiiklinikhi.

Kutheni usebenzisana neJinan Meiyi Biotechnology?

Ikomkhulu eJinan, kwiPhondo laseShandong, eChina, kwaye lisebenza njenge-subsidiary yePacific Kangtai Scientific Instruments (Jinan) Co., Ltd., IJinan Meiyi Biotechnology Co., Ltd. inikezelwe kuphando, inkxaso yophuhliso, kunye norhwebo lwetekhnoloji ye-bioactive. Sizibeka kwindawo ekudityaniswa kuyo ubungqongqo bezenzululwazi kunye nokuphendula kwintengiso-sisebenza njengesixhobo esithenjiweyo sokwenza izinto ezintsha kulo lonke ukhathalelo lobuqu lwehlabathi kunye nekhonkco lexabiso leyeza lobuhle.

Ishishini lethu elingundoqo lakhiwe malunga neentsika ezimbini ezincedisayo: ukubonelela ngezinto zokuthambisa kunye ne-bioactive ekrwada, kunye nokuhanjiswa kwezinto zokuthambisa eziphambili kunye neemveliso zobuhle zonyango. Ngaphakathi kwecandelo lezinto eziluhlaza, sigxininise ngokukodwa kwizithako ezisebenzayo kunye namacandelo asebenzayo asetyenziswa kuphuhliso loqulunqo. Asizibandakanyi ngokwethu ukwenza imathiriyeli ekrwada kodwa sisebenza njengeqhinga lokufumana kunye neqabane lokuhambisa eliqinisekisiweyo lomgangatho.

• Ucoceko olungagungqiyo kunye noKhetho: Iikhrayitheriya zethu zokukhetha ezingqongqo zisekelwe kwidatha esebenzayo, iiprofayili zozinzo, kunye nokuhambelana nemigangatho yokuqulunqwa kwale mihla. Siqinisekisa ukungcola okuncinci, ukwandisa i-biocompatibility kunye ne-bioactivity.
• Ikhonkco lonikezelo lwehlabathi: Ukusebenzisa ubudlelwane bentsebenziswano bexesha elide nababoneleli abavunyiweyo bamazwe ngamazwe, siqinisekisa ufikelelo olungaguquguqukiyo kwizinto eziphucukileyo, ezithobela imithetho, kunye nezixhobo eziqinisekisiweyo ngokwenzululwazi.
• UbuGcisa boBugcisa: Iqela lethu lezinto zenzululwazi kunye neenjineli zibonelela ngokubonisana kweengcali malunga nokuqulunqwa kunye nokusebenza. Sijonga ngenkuthalo iintsingiselo ezivelayo kwisayensi yesithako se-bioactive kunye nophando lwedermatological.
• Inkonzo eJoliswe kwiNtsebenziswano: Sisebenzela abathengi kulo lonke elase-Asiya, iYurophu, kunye noMntla Melika, ngamandla athile ekuxhaseni iilabhoratri ze-R&D, ii-CDMO, kunye neekliniki zobuhle. Ifilosofi yethu yenkonzo igxininisa intsebenziswano yobugcisa, ulwazi lolawulo, kunye nokuphendula ngokukhawuleza.
• Ukuthotyelwa kweHlabathi: Iimveliso zethu zithathwe kubavelisi ngokuthobela imigangatho yamazwe ngamazwe, ukwenza lula ukufikelela kwimarike yehlabathi. Isixhobo ngasinye sikhatshwa ngamaxwebhu apheleleyo obugcisa, kubandakanywa izatifikethi zokuhlalutya kunye namaphepha edatha yokhuseleko.

Isiphelo kunye naManyathelo alandelayo

I-High Purity 45S5 i-Bioactive Glass imele ilitye lembombo kwiyeza langoku lokuhlaziya. Ubuchule bayo obukhethekileyo bokuzimanya nezicubu, ukuvuselela ukukhula ngokutsha, kunye nokuxhathisa usulelo buyenza ibaluleke kakhulu kunyango lwamathambo, kunyango lwamazinyo, nakukhathalelo lwamanxeba.
