Mukuvandudzwa kuri kuitwa nhasi kwenzvimbo dzakawanda dzakadai sesainzi yezvinhu uye biomedicine, chitosan, sechigadzirwa chezvipenyu chezvisikwa, iri kuratidza mikana yakakura yekushandiswa nemabasa ayo akanaka uye mabasa akasiyana-siyana. Chitosan, chinhu chinonzi polysaccharide chinotorwa kubva mumagoko emhuka dzakadai sema shrimps nemakaka, chine mhando dzakasiyana dzemakemikari nemuviri, nokudaro ichiisa hwaro hwakasimba hwekushandiswa kwayo munzvimbo dzakasiyana-siyana. I. Kugona Kusingaperi MuBasa Rehutano MuBasa rehutano, mikana yekushandiswa kwechitosan inoonekwa zvikuru. Ine hukama hwakanaka uye kuora kwezvipenyu, izvo zvinoita kuti ive chinhu chekurapa chakakodzera. 1. Tariro Itsva Yekuchengetedza Maronda - Panyaya yekuporesa maronda, chitosan inoratidza mabhenefiti akasiyana. Inogona kuumba nharaunda diki inobatsira kufamba kwemasero uye kuwanda, ichikurumidzisa maitiro ekuporesa maronda. Uyezve, chitosan ine basa rekurwisa mabhakitiriya uye inogona kudzivirira kukura kwemabhakitiriya akajairika paronda, akadai seStaphylococcus aureus neEscherichia coli. Parizvino, mamwe machira echitosan ane hunyanzvi apinda muchikamu chekuyedzwa kwekiriniki uye anotarisirwa kuunza mhedzisiro iri nani yekurapa kuvarwere vane maronda asingaperi, kutsva, nezvimwewo. 2. Kuvandudzwa muSistimu dzeKuendesa Mishonga - Chitosan ine mukana mukuru mumunda wekuendesa mishonga. Inogona kugadzirwa kuita nanoparticles kana microspheres kuti iunganidze mamorekuru akasiyana-siyana emishonga. Aya machira echitosan anogona kudzivirira mishonga kubva mukuora nema enzymes mumuviri uye anogona kuwana kuburitswa kwemishonga kwakarongwa munzvimbo dzakati dzemuviri. Izvi zvakakosha zvikuru kuminda inoda kutumirwa kwemishonga kwakanyatsojeka, senge kurapwa kwekenza uye kurapwa kwezvirwere zvemwoyo. Semuenzaniso, mukuendesa mishonga yekurwisa kenza, machira echitosan nanoparticle anogona kutakura mishonga nemazvo kuenda kumatumbu egomarara, achiwedzera huwandu hwemishonga panzvimbo yegomarara uku achideredza mhedzisiro pamatishu akajairwa. II. Nyeredzi Inokura muIndasitiri yeChikafu 1. Kuchengetedza Chikafu uye Kurongedza - Muindasitiri yechikafu, chitosan iri kubuda. Nekuda kwehunhu hwayo hwekurwisa mabhakitiriya uye kugona kugadzira mafirimu anodyiwa, inogona kushandiswa kuchengetedza chikafu nekurongedza. Mafirimu eChitosan anogona kudzivirira kupinda kweokisijeni, hunyoro, uye tupukanana, zvichiita kuti chikafu chirambe kwenguva refu. Semuenzaniso, pamichero mitsva nezvigadzirwa zvenyama, kushandiswa kwechitosan packaging kunogona kuderedza njodzi yekuora uye kuora uye kuderedza kurasikirwa nechikafu. 2. Zvinowedzera Kudya Zvinoshanda - Chitosan inogonawo kushandiswa sechinhu chinobatsira pakudya. Ine mabasa ekudzora mafuta eropa uye kuderedza cholesterol uye inotarisirwa kugadzirwa kuva rudzi rutsva rwechikafu chine hutano. Dzimwe ongororo dzakaratidza kuti chitosan inogona kusunga mafuta necholesterol muura, ichidzivirira kuti asanyurwe nemuviri wemunhu, nokudaro ichitamba basa guru mukuchengetedza hutano hwemwoyo. III. Mubatsiri Anokwanisa Mumunda weKudzivirirwa Kwezvakatipoteredza 1. Kurapa Mvura Yakasviba - Panyaya yekuchengetedzwa kwezvakatipoteredza, chitosan inoratidza kugona kunoshamisa mukurapa mvura yakasviba. Inogona kunyudza maion esimbi anorema akadai selead, mercury, uye cadmium mumvura yakasviba uye inogonawo kubvisa tsvina yeorganic mumvura yakasviba. Nheyo yekunyudza inobva pakubatana pakati pemapoka anoshanda akadai semapoka eamino nehydroxyl pamorekuru yechitosan netsvina. Nekuda kwezvinodiwa zvakanyanya zvekuchengetedza nharaunda, kushandiswa kwechitosan mukuchenesa mvura yakasviba mumaindasitiri kunotarisirwa kusimudzirwa zvakanyanya. 2. Kuvandudza Ivhu - Chitosan inewo mhedzisiro yakanaka pakuvandudza ivhu. Inogona kuvandudza kugona kwemvura nefetereza kuchengetedza ivhu, kukurudzira kushanda kwezvipembenene zvevhu, uye kuvandudza chimiro chevhu. Mune kumwe kugadziriswa kwevhu rakasviba, chitosan inogona kusanganiswa nezvinhu zvinokuvadza muvhu, zvichideredza kuwanikwa kwazvo, nokudaro ichidzorera ivhu kuhutano hwakanaka. Kunyangwe mukana wekushandisa chitosan wakakura, ichiri kutarisana nematambudziko pari zvino. Semuenzaniso, mutengo wekubvisa chitosan wakakwira, uye maitiro ekugadzirwa kwayo kukuru mumaindasitiri anoda kugadziriswa zvakanyanya. Pamusoro pezvo, mune mamwe mashandisirwo, kugadzikana kwekushanda kwechitosan kunofanirwa kuvandudzwa zvakanyanya. Nekudaro, nekuvandudzwa kuri kuramba kuchiitwa kwesainzi netekinoroji uye kutsvagisa kwakadzama, masangano mazhinji esainzi nemakambani ari kutsvaga mukana wechitosan. Imwe nyanzvi yakati: “Tinotenda kuti mumakore mashoma anotevera, nekubudirira kwetekinoroji, chitosan ichashandiswa zvakanyanya muminda yakawanda, zvichiunza shanduko huru kuhutano hwevanhu, chikafu, nharaunda, nezvimwewo.” Chitosan, ine zvayakanakira zvakasiyana muhutano, indasitiri yechikafu, kuchengetedzwa kwezvakatipoteredza nedzimwe minda, hapana mubvunzo kuti imhando yezvinhu zvipenyu zvechisikigo zvine mukana mukuru wekuvandudza, uye mikana yekushandisa kwayo yakazara nemikana isingaperi.
