Mu chitukuko cha masiku ano cha madera ambiri monga sayansi ya zinthu ndi biomedicine, chitosan, monga chinthu chachilengedwe chachilengedwe, ikuwonetsa mwayi wogwiritsidwa ntchito kwambiri ndi makhalidwe ake abwino komanso ntchito zosiyanasiyana. Chitosan, chinthu cha polysaccharide chochokera ku zipolopolo za crustaceans monga nkhanu ndi nkhanu, chili ndi mitundu yosiyanasiyana ya mankhwala ndi zinthu zakuthupi, motero chimayika maziko olimba ogwiritsira ntchito m'magawo osiyanasiyana. I. Kuthekera Kopanda Malire M'munda wa Zaumoyo Mumunda wa Zaumoyo, mwayi wogwiritsa ntchito chitosan ndi wowonekera kwambiri. Ili ndi mgwirizano wabwino kwambiri wa biochemical ndi biodegradable, zomwe zimapangitsa kuti ikhale chinthu chabwino kwambiri chachipatala. 1. Chiyembekezo Chatsopano cha Chisamaliro cha Mabala - Ponena za kuchiritsa mabala, chitosan ikuwonetsa zabwino zapadera. Imatha kupanga malo ang'onoang'ono omwe amathandiza kusamuka kwa maselo ndi kuchulukana, ndikufulumizitsa njira yochiritsira mabala. Kuphatikiza apo, chitosan ili ndi ntchito inayake yoletsa mabakiteriya ndipo imatha kuletsa kukula kwa mabakiteriya wamba pabala, monga Staphylococcus aureus ndi Escherichia coli. Pakadali pano, ma dressing ena apamwamba a chitosan alowa mu gawo loyesera lachipatala ndipo akuyembekezeka kubweretsa zotsatira zabwino za chithandizo kwa odwala omwe ali ndi mabala osatha, kupsa, ndi zina zotero. 2. Zatsopano mu Machitidwe Operekera Mankhwala - Chitosan ilinso ndi kuthekera kwakukulu pantchito yopereka mankhwala. Itha kupangidwa kukhala tinthu tating'onoting'ono kapena ma microspheres kuti iphatikize mamolekyu osiyanasiyana a mankhwala. Zonyamula chitosan izi zimatha kuteteza mankhwala kuti asawonongeke ndi ma enzymes m'thupi ndipo zimatha kupangitsa kuti mankhwala azitulutsidwa bwino m'malo enaake a thupi. Izi ndizofunikira kwambiri m'magawo omwe amafunikira kuperekedwa kwa mankhwala molondola, monga chithandizo cha khansa ndi chithandizo cha matenda a mtima. Mwachitsanzo, popereka mankhwala oletsa khansa, zonyamula chitosan nanoparticle zimatha kunyamula mankhwala molondola kupita ku minofu ya chotupa, ndikuwonjezera kuchuluka kwa mankhwala pamalo otupa pomwe zimachepetsa zotsatira zoyipa pa minofu yachibadwa. II. Nyengo Yokwera M'makampani Ogulitsa Chakudya 1. Kusunga Chakudya ndi Kuyika - Mumakampani ogulitsa chakudya, chitosan ikubwera. Chifukwa cha mphamvu zake zotsutsana ndi mabakiteriya komanso kuthekera kopanga mafilimu odyedwa, ingagwiritsidwe ntchito posunga chakudya ndi kuyika. Mafilimu a Chitosan amatha kuletsa bwino kulowa kwa mpweya, chinyezi, ndi tizilombo toyambitsa matenda, zomwe zimapangitsa kuti chakudya chikhale cholimba. Mwachitsanzo, pa zipatso zatsopano ndi nyama, kugwiritsa ntchito chitosan packaging kungachepetse chiopsezo cha kuwonongeka ndi kutayika kwa chakudya. 2. Zowonjezera Zakudya Zogwira Ntchito - Chitosan ingagwiritsidwenso ntchito ngati chowonjezera cha chakudya chogwira ntchito. Ili ndi ntchito zowongolera mafuta m'magazi ndikuchepetsa cholesterol ndipo ikuyembekezeka kupangidwa kukhala mtundu watsopano wa chakudya chopatsa thanzi. Kafukufuku wina wasonyeza kuti chitosan imatha kumangirira ku mafuta ndi cholesterol m'matumbo, kuwaletsa kuti asatengeke ndi thupi la munthu, motero imagwira ntchito yoteteza thanzi la mtima. III. Wothandizira Wokhoza M'munda Woteteza Zachilengedwe 1. Kuchiza Madzi Otayidwa - Ponena za kuteteza zachilengedwe, chitosan imasonyeza luso lapadera pochiza madzi otayidwa. Imatha kuyamwa ma ayoni olemera achitsulo monga lead, mercury, ndi cadmium m'madzi otayidwa ndipo imathanso kuchotsa zinthu zoipitsa zachilengedwe m'madzi otayidwa. Mfundo yoyamwa imachokera pa mgwirizano pakati pa magulu ogwira ntchito monga magulu a amino ndi hydroxyl pa molekyulu ya chitosan ndi zoipitsa. Ndi zofunikira zoteteza chilengedwe zomwe zikuchulukirachulukira, kugwiritsa ntchito chitosan poyeretsa madzi otayira m'mafakitale kukuyembekezeka kupitilizidwa. 2. Kukonza Dothi - Chitosan ilinso ndi zotsatira zabwino pa nthaka. Ikhoza kukweza mphamvu yosunga madzi ndi feteleza m'nthaka, kulimbikitsa ntchito za tizilombo toyambitsa matenda m'nthaka, ndikukonzanso kapangidwe ka nthaka. Pakukonzanso nthaka yoipitsidwa, chitosan imatha kuphatikizana ndi zinthu zovulaza m'nthaka, kuchepetsa kupezeka kwawo, motero kubwezeretsa nthaka kukhala yathanzi. Ngakhale kuti mwayi wogwiritsa ntchito chitosan ndi waukulu kwambiri, pakadali pano ikukumana ndi zovuta zina. Mwachitsanzo, mtengo wochotsera chitosan ndi wokwera, ndipo njira yopangira mafakitale akuluakulu ikufunika kukonzedwanso. Kuphatikiza apo, m'magwiritsidwe ena, kukhazikika kwa magwiridwe antchito a chitosan kuyenera kukulitsidwa kwambiri. Komabe, ndi chitukuko chopitilira cha sayansi ndi ukadaulo komanso kafukufuku wozama, mabungwe ambiri ofufuza zasayansi ndi mabizinesi akufufuza mwachangu kuthekera kwa chitosan. Katswiri wina anati: “Tikukhulupirira kuti m'zaka zingapo zikubwerazi, ndi kupita patsogolo kwa ukadaulo, chitosan idzagwiritsidwa ntchito kwambiri m'magawo ambiri, zomwe zimabweretsa kusintha kwakukulu pa thanzi la anthu, chakudya, chilengedwe, ndi zina zotero.” Chitosan, yokhala ndi ubwino wake wapadera mu chisamaliro chaumoyo, mafakitale azakudya, kuteteza chilengedwe ndi madera ena, mosakayikira ndi chinthu chachilengedwe chokhala ndi kuthekera kwakukulu kokukula, ndipo mwayi wogwiritsidwa ntchito uli wodzaza ndi mwayi wopanda malire.
