Indlela ethembisayo yokuphucula ukhuseleko kunye nokusebenza kakuhle kokuhanjiswa kweziyobisi emehlweni.
Enye yeenzuzo eziphambili zabathwali beziyobisi ezisekelwe kwi-nanotechnology kukukwazi kwabo ukukhusela kunye nokuzinzisa ii-arhente zonyango. Amayeza ee-ocular ahlala ephantsi komgangatho kunye ne-bioavailability ephantsi ngenxa yokuguquguquka kolwelo kunye nomsebenzi we-enzymatic. Ii-nanocarriers, ezifana ne-nanoparticles kunye ne-liposomes, zinokufaka iziyobisi, zikhusele ukuthotywa kwe-enzymatic kunye nokuphucula ukuzinza kwazo ngexesha lokuhamba ukuya kwizicubu ezijoliswe kuyo. Le propati ibonakalise ukuba luncedo kumachiza anokunyibilika kakubi kwamanzi okanye ubomi obufutshane obufutshane.
Ngaphezu koko, ubungakanani obuncinci be-nanocarriers buvumela ukuba bangene ngokufanelekileyo kwizithintelo zamehlo. I-cornea, umzekelo, ibeka umceli mngeni obalulekileyo wokuhanjiswa kweziyobisi ngenxa yomgangatho wayo ongaphandle we-lipophilic. I-Nanoparticles enokuguqulwa okufanelekileyo kwendawo inokuwela i-cornea ngokufanelekileyo, ivumela ukuba izidakamizwa zifikelele kwigumbi langaphambili kwaye zijolise kwizicubu ezithile ze-ocular.
I-Nanotechnology ikwaququzelele ukuhanjiswa kweziyobisi okuzinzileyo emehlweni. Ngokulungelelanisa ukubunjwa kunye nesakhiwo se-nanocarriers, abaphandi banokuqulunqa iinkqubo ezikhupha iziyobisi kwizinga elilawulwayo, ukugcina amanqanaba onyango ixesha elide. Le ndlela inenzuzo ngakumbi kwizifo zamehlo ezingapheliyo ezifana ne-glaucoma kunye nokuphazamiseka kwe-retinal, apho ukulawulwa kweziyobisi rhoqo kunokuba ngumthwalo kwizigulane.
Ukongeza ekuphuculeni ukuhanjiswa kweziyobisi, i-nanotechnology inika ithuba lonyango olujoliswe kuyo kwi-ophthalmology. Ukusetyenziswa kwee-nanocarriers ezine-ligands okanye izilwa-buhlungu zenza ukuba unikezelo lwechiza olujoliswe kwindawo ethile. Ezi ligands ziyakwazi ukuqaphela i-receptors ethile okanye i-antigens ekhoyo kwizicubu ze-ocular ezigulayo, ziqinisekisa ukuba iyeza lifikelela kwithagethi ekujoliswe kuyo ngokuchaneka okuphezulu. I-nanocarriers ekujoliswe kuyo ibambe isithembiso esikhulu kunyango lweemeko ezifana ne-ocular tumors kunye nokuphazamiseka kwe-neovascular, apho unyango lwendawo lungundoqo.
Ngelixa i-nanotechnology kunikezelo lweziyobisi lwamehlo lunamandla amakhulu, imingeni isekhona, ngakumbi malunga nokhuseleko lwexesha elide kunye nolwamkelo lolawulo. Uphando oluqhubekayo lujolise ekujonganeni neenkxalabo ezinxulumene ne-biocompatibility, ubuthi kunye nokupheliswa kwee-nanocarriers. Ngaphaya koko, intsebenziswano phakathi kwezemfundo, ishishini kunye namaqumrhu olawulo kubalulekile ukukhawulezisa ukuguqulelwa kwe-nanotechnology-based ocular therapies ukusuka kwilabhoratri ukuya kwiklinikhi.
Ukuqukumbela, i-nanotechnology iye yazisa izisombululo ezintsha nezisebenzayo kwimingeni yokuhanjiswa kweziyobisi emehlweni. Ukususela ekuphuculeni ukuzinza kweziyobisi kunye ne-bioavailability ukwenzela ukuba kusetyenziswe iindlela zonyango ezijoliswe kuzo kunye nezizinzileyo, i-nanotechnology ilungele ukuguqula unyango lwezifo zamehlo. Ukuqhubela phambili okuqhubekayo kule nkalo ngokuqinisekileyo kuya kukhokelela ekuhanjisweni kwamachiza okukhuselekileyo kunye nokusebenza kakuhle kwamehlo, ukuphucula umgangatho wobomi bezigulane ezingenakubalwa kwihlabathi jikelele.
