Hauv kev txhim kho niaj hnub no ntawm ntau cov liaj teb xws li cov khoom siv science thiab biomedicine, yog qhia tau ntau yam kev cia siab ua ke nrog nws cov khoom muaj ntau yam zoo nkauj thiab kev ua haujlwm zoo. Chitosan, ib cov tshuaj polysaccharide tawm los ntawm cov plhaub ntawm crustaceans xws li crustaceans xws li cw thiab lub zog, muaj ntau yam khoom siv rau nws daim ntawv thov hauv ntau daim teb. I. Cov peev xwm txwv tsis pub muaj kev kho mob teb nyob rau hauv thaj teb kho mob hauv Healthcare daim teb, daim ntawv thov kev cia siab ntawm Chitosan yog qhov tseem ceeb. Nws muaj biocompatibility zoo heev thiab biodegradability, uas ua rau nws muaj cov khoom siv kho mob zoo tshaj. 1. Kev cia siab tshiab rau kev saib xyuas zoo - Hais txog kev ua kom zoo, Chitosan qhia tau cov txiaj ntsig zoo. Nws tuaj yeem tsim cov micro - ib puag ncig ua kom haum rau cell tsiv teb chaws thiab prodiferation, nrawm nrawm rau lub qhov txhab - kho txheej txheem. Ntxiv mus, Chitosan muaj qee yam haujlwm antibacterial thiab tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob sib txawv ntawm qhov txhab ntawm lub qhov txhab, xws li Staphyrococcus aureus thiab Eschchia Coli. Tam sim no, qee cov kev hnav ris tsho siab tshaj plaws tau nkag mus rau cov kev kho mob theem - Chitosan kuj muaj peev xwm muaj peev xwm muaj peev xwm ua tau cov tshuaj. Nws tuaj yeem ua rau hauv nanoparticles lossis microsugheres rau encapsulate ntau yam tshuaj molecules. Cov neeg chitosan no tuaj yeem tiv thaiv cov tshuaj los ntawm kev saib tsis taus los ntawm cov enzymes hauv lub cev thiab tuaj yeem ua tiav cov tshuaj tso tawm hauv lub cev ib puag ncig. Qhov no yog qhov tseem ceeb tshaj plaws rau cov teb uas yuav tsum tau xa cov tshuaj muaj txiaj ntsig, xws li kev kho mob qog noj ntshav thiab mob plawv kev kho mob. Piv txwv li, hauv kev xa tawm ntawm cov tshuaj tiv thaiv kab mob, chitosan nanoparticle cov neeg nqa khoom mus rau cov nqaij ntswg Ii. Lub hnub qub microscoping hauv kev lag luam khoom noj khoom haus 1. Khoom noj khaws cia thiab ntim khoom, chitosan tawm tuaj. Vim nws cov tshuaj tua kabmob thiab muaj peev xwm ua cov yeeb yaj kiab uas muaj ntxhiab tsw, nws tuaj yeem siv rau cov khoom noj kom txuag tau thiab ntim khoom. Chitosan cov yeeb yaj kiab tuaj yeem tiv thaiv kev ntxeem tau ntawm cov pa, noo noo, thiab cov kab mob me, ua kom lub neej ua haujlwm ntawm cov zaub mov. Piv txwv li, rau cov txiv hmab txiv ntoo thiab nqaij tshiab, siv cov ntim chaitosan tuaj yeem txo qhov kev pheej hmoo ntawm kev piam sij thiab tsis zoo thiab txo qis nyiaj txiag poob. 2. Cov zaub mov noj ua haujlwm ntxiv - Chitosan kuj tseem siv tau ua cov zaub mov ua haujlwm ntxiv. Nws muaj cov haujlwm tswj cov ntshav thiab txo cov roj cholesterol thiab yuav tsum tsim mus rau hom khoom noj kom zoo. Qee qhov kev tshawb fawb tau qhia tias Chitosan tuaj yeem khi cov rog thiab cov roj av cholesteroled los ntawm tib neeg lub cev, tiv thaiv kev ua haujlwm hauv kev tiv thaiv kev noj qab haus huv plawv. III. Tus pab cuam muaj peev xwm ua rau muaj kev tiv thaiv ib puag ncig. Nws tuaj yeem adsorb cov hlau hnyav xws li txhuas, Mercury, thiab Cadmium hauv dej qias neeg thiab tseem tuaj yeem tshem tawm cov organic paug hauv dej qias neeg. Cov kab lus tshaj tawm yog nyob ntawm kev sib cuam tshuam ntawm pawg ua haujlwm xws li amino thiab hydroxyl pawg ntawm Chitosan Molecule thiab cov kuab paug. Cov kev tiv thaiv kev tiv thaiv ib puag ncig ib puag ncig ib puag ncig, kev siv Chitosan hauv kev kho kom muaj kev kho kom zoo nkauj yog xav tau kev txhawb nqa ntxiv. 2. Av txhim kho - Chitosan tseem muaj kev txhim kho zoo rau cov av. Nws tuaj yeem txhim kho cov dej - thiab - chiv - tuav tau peev xwm ntawm cov av, txhawb nqa cov kev ua si ntawm cov av cov kab ke, thiab txhim kho cov av qauv. Hauv qee qhov kev ua paug hauv av av, Chitosan tuaj yeem sib xyaw nrog cov av muaj kev phom sij hauv av, txo qis, muaj cov av rau lub xeev noj qab nyob zoo. Txawm hais tias daim ntawv thov kev cia siab ntawm Chitosan yog qhov dav heev, nws tseem ntsib qee qhov kev cov nyom ntawm tam sim no. Piv txwv li, extraction tus nqi ntawm Chitosan yog tus muaj mob siab, thiab cov txheej txheem ntawm nws cov loj - kev lag luam muaj kev xav tau zoo dua. Ib qho ntxiv, hauv qee cov ntawv thov, kev ua yeeb yam ruaj ntseg ntawm Chitosan yuav tsum tau txhim kho ntxiv. Txawm li cas los xij, nrog kev txhim kho kev kawm ntxiv ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tshawb fawb tob thiab kev lag luam tshawb nrhiav cov peev xwm ntawm Chitosan. Ib tug kws tshaj lij tau hais tias: "Peb ntseeg tias nyob rau ob peb xyoos tom ntej no, Chitosanologce, nqa cov kev hloov pauv loj hauv tib neeg kev noj qab haus huv, zaub mov, ib puag ncig, thiab lwm yam." Chitosan, nrog nws cov cim tshwj xeeb hauv kev tiv thaiv kev kho mob, kev tiv thaiv kev lag luam ib puag ncig thiab lwm daim teb, yog nws cov ntaub ntawv txhim kho zoo kawg nkaus.
