Mesoporous Silicon Dioxide 1. Umhlahlandlela Womkhiqizo (Product Overview) 1.1 Izincazelo eziyisisekelo Zhongqi Mesoporous Silica, umkhiqizo wokwelapha osebenzayo okhiqizwa ngenqubo ye-sol-gel, ubonakala njengomphezulu omhlophe ongenamumo. Izici zawo ezichazayo zifaka phakathi isakhiwo esijwayelekile se-mesoporous esinezakhiwo ezivulekile ezisukela ku-2 kuya ku-50nm kanye nendawo ethile enkulu kakhulu. Lo mkhiqizo ubonisa amandla aphezulu okulayisha imithi, izinga lokukhululwa okulawulwayo, kanye nokuhambisana okuhle kwe-biocompatibility, ngenkathi uhlala ungasebenzi ngokwemikhakha yephilisi. Njengoba kunjalo, usebenza njengomkhiqizo oyinhloko wokwakha izinhlelo zokulethwa kwemithi ezinembile. 1.2 Izinzuzo eziyisisekelo Njengomkhiqizo ophakeme wokwelapha, Zhongqi Mesoporous Silica uphumelela ekuxazululeni izinselelo zezimboni ezifana nokungafaneleki kahle nokuphila okuphansi kwemithi ezinhlelweni ezijwayelekile. Ngokulawula kahle isakhiwo sezakhiwo nezici zendawo, ivumela ukulayisha imithi kahle nokukhululwa okuhlakaniphile, kuthuthukisa kakhulu ukufinyelela kwe-biological ngenkathi kunciphisa imiphumela emibi. Umkhiqizo uhambisana nezindinganiso eziqinile zomhlaba jikelele zokwelapha, uhlinzeka ngensiza eyinhloko yokwakha izinhlelo ezintsha zokwakha imikhiqizo kanye nokuthuthukiswa kwemithi yejenereyikhi ephezulu. 2. Izici Zomkhiqizo (Product Characteristics) 2.1 Izinzuzo zesakhiwo nezokusebenza •Isakhiwo se-mesoporous esiqondile: usayizi wezakhiwo ungashintshwa ngokuqhubekayo ukusuka ku-5 kuya ku-30nm, ukusatshalaliswa kosayizi lwezakhiwo kuhlangene (ukuphambuka ≤2nm), indawo ethile ye-BET ingafinyelela ku-300-1000m²/g, kanti ivolumu ye-mesoporous ingafinyelela ku-2.0cm³/g, ihlinzeka ngendawo eyanele yokulayisha ama-molecule emithi. •Ukulawula ukukhululwa okuhlakaniphile: Ngokusebenzisa ukuguqulwa kwendawo kwezakhiwo ezithintekayo ze-pH, ezithintekayo ze-enzyme nezinye "izivalo eziphendulayo", ukukhululwa okukhethekile kwemithi ezindaweni ezihlosiwe kungafezeka, futhi izinga lokukhululwa lingalawulwa ngokuqondile nge-±5% emithonjeni. •Ukuhambisana okuhle kwe-biocompatibility: Ukuhlanzeka kwe-SiO₂ kuphakathi kuka-99.0%, okuqukethwe kwezimbiwa ezinzima kuphansi kuka-10ppm, okuqukethwe kwe-arsenic kuphansi kuka-3ppm, futhi akukho ukulimala okubonakalayo kwamaseli okuqinisekiswa ngovivinyo lwe-cytotoxicity, okuhambisana nezindinganiso zokuphepha zezinto zokwelapha. •Ukuguqulwa okuphezulu: indawo ingaxhunywa ngokuvumelanayo nezinsiza ezifana ne-folic acid, PEG kanye ne-peptide ukuze kuqinisekiswe ukulethwa okuhlosiwe, futhi ukusebenza kokuhlanganiswa okuhlosiwe kuphakathi kuka-5-8 izikhathi phezulu kunezithuthi ezijwayelekile. 2.2 Ukuqinisekiswa kwezinqubo Inqubo yokwakha esekelwe kumasampuli we-cationic surfactant ifinyelela izakhiwo ze-mesoporous ezihambisanayo kakhulu ngokulawula kahle izinga lokushisa, i-pH, kanye nokugxila kwamasampuli. Inqubo yokukhiqiza ihambisana ngokuqinile nezindinganiso ze-GMP enezinhlelo zokubheka usayizi lwezakhiwo ezihlanganisiwe, iqinisekisa ukulawulwa kwekhwalithi okuqinile ngokuhlolwa kweqoqo ngalinye ukuze kugcinwe izimo ezinzile nezilawulwayo phakathi nesikhathi sokukhiqiza. 2.3 Indima eyinhloko 1.Usizo lokugeleza: kuthuthukisa ukugeleza kwe-powder ye-API, ukuze umehluko wesisindo sokugcwalisa samathayili ulawulwe phakathi kuka-±3%, futhi ukusebenza kokucindezela amathayili kwanda ngo-20%; 2.Ukuvimbela ukujolisa: kuvimba impahla ekubambeni kumphini, kunciphisa ukuvela kokuphuka nokubambeka, ikakhulukazi efanelekile ekulungiseleleni izithako ze-herbal ezinamafutha aphezulu; 3.Ukuzinza: ibamba umswakama omncane kumathayili, ibambezele ukwehla kwezithako ezisebenzayo, futhi ikhulise isikhathi sokuphila kwemithi sibe yizinyanga eziyi-12-24; 4.Umthwali wokukhululwa: Ngokulawula isakhiwo sezakhiwo ukuze kulungiswe izinga lokukhululwa kwemithi, ukwengeza u-0.2% ekwakhiweni kwamathayili okukhululwa okuqhubekayo kungafinyelela ukukhululwa kwemithi isikhathi eside. 3. Ipharamitha ebalulekile yezobuchwepheshe (KTP) Izingxenye zepharamitha Ububanzi bezinkomba umthetho wokuhlola Okuqukethwe kwe-SiO₂ (ngemuva kokushiswa) ≥99.0% USP-NF <281> Indawo ethile ye-BET (m²/g) 300-1000 Indlela yokumunca ye-BET I-porosity (cm³g) 0.8-2.0 Umthetho we-BJH usayizi ophakathi (nm) 5-30 Umthetho we-BJH Ukulahleka kwesisindo esomile (105℃,2h) ≤6.0% ukuhlaziywa kwe-gravimetric Okuqukethwe kwezimbiwa ezinzima (ppm) ≤10 Ukuhlaziywa kokumunca kwe-atomic 4. Izinkambu zokusetshenziswa (Application Fields) 1. Umthwali wemithi: Imithi ye-chemotherapy enezinga eliphezulu (njenge-doxorubicin) ingakhululwa ngokunembile ngokuphendula kwe-pH/ukushisa ukuze kuncishiswe ukulimala kumaseli ajwayelekile; imithi engaxhunywanga (njenge-paclitaxel) ingafakwa ukuze kuthuthukiswe ukuxhunywa nokufinyelela kwe-biological. 2. I-vector ye-genetic/vaccine: ivikela i-siRNA ne-plasmid DNA ekwehliseni, ithuthukise ukutholwa kwamaseli ngokuguqulwa ukuze kuqinisekiswe ukulethwa okuhlosiwe; ibamba i-antigen ye-vaccine futhi ikhulise isikhathi sokugcina ukuze iqinise impendulo ye-immunity. 3. Ukuhlola nokwelapha okuhlanganisiwe: Layisha ama-dyes aphuzi kanye nezinsiza zokuhlola i-MRI/CT ukuze kwakhiwe ipulatifomu yokuhlola nokwelapha yokubheka ngesikhathi sokulethwa kwemithi nezinguquko ezithinta. 4. Ukuvimbela amagciwane nokulungiswa kwezicubu: ilayisha ama-ion e-silver kanye nezidakamizwa zokuvimbela amagciwane ukuze ivimbe amagciwane isikhathi eside (ngokwelashwa kwezilonda); isakhiwo esinezakhiwo simisela i-extracellular matrix, sisekele ukukhula nokuhlukaniswa kwamangqamuzana, futhi sithuthukisa ukulungiswa kwezicubu/skin. 5.
