Kutheni kufuneka unyango lomphezulu we-TC kwizinto ezityiwayo zenkcubeko yeseli?
Kukho iindidi ngeendidi zeeseli, ezinokuthi zahlulwe zibe ziiseli ezibambelelayo kunye neeseli zokunqunyanyiswa ngokwemigaqo yenkcubeko Iiseli ezimisiweyo ziiseli ezikhula ngokuzimeleyo kumphezulu wenkxaso, kwaye zikhule ngokunqunyanyiswa kwindawo yenkcubeko, njenge-lymphocytes Iiseli ezibambelelayo. ziiseli ezibambelelayo, nto leyo ethetha ukuba ukukhula kweeseli kufuneka kube nendawo yokuxhasa enamathelayo.Banokukhula kuphela kwaye bavelise kwakhona kulo mhlaba ngokuxhomekeke kwizinto zokubambelela ezifihliweyo ngokwabo okanye ezibonelelwe kwinkcubeko yenkcubeko.Uninzi lweeseli zezilwanyana zezeeseli ezibambelelayo.
Ngaphambili, uninzi lwezinto ezityiwayo zenkcubeko yeseli kwimarike zenziwe ngeglasi, eyayiyi-hydrophilic, ngoko ke umphezulu awuzange ufune unyango olukhethekileyo, nangona kunjalo, kwinkqubo yokusetyenziswa yokwenyani, kukho ukusilela okunjengokungahlambuluki kunye nokulula ukungcolisa isampula Nge. uphuhliso olukhawulezayo lwesayensi kunye nethekhinoloji, izixhobo ezahlukeneyo zepolymer (ezifana nepolystyrene PS) ziye zatshintsha kancinci kancinci izinto zeglasi kwaye zaba zizinto ezisisiseko zokusetyenzwa kwezinto ezisetyenziswa kwinkcubeko yeseli.
I-Polystyrene yi-amorphous random polymer kunye nokungafihli.Iimveliso zayo ziphezulu kakhulu elubala, kunye nokudluliselwa okungaphezulu kwe-90%, enceda ekujongeni imeko yenkcubeko yeeseli phantsi kwemakroskopu.Ukongeza, ineenzuzo zombala olula, ukusetyenzwa kakuhle kwe-fluidity, ukuqina okuhle kunye nokuchasana kokubola kweekhemikhali, Nangona kunjalo, umphezulu wepolystyrene yi-hydrophobic.Ukuze kuqinisekiswe ukuba iiseli ezibambelelayo zinokuncamathela kumphezulu wezinto ezisetyenziswayo kakuhle, umphezulu wezinto ezisetyenziswayo kwinkcubeko yeeseli kufuneka zifumane unyango olukhethekileyo lokuguqulwa.Izinto ze-Hydrophilic zingeniswa kumphezulu ukulungelelanisa ukukhula kunye nokuveliswa kweeseli ezinamathele.Olu nyango lubizwa ngokuba yi-TC surface treatment TC unyango lusebenza kwizitya zokukhuliswa kweeseli, iipleyiti zokukhuliswa kweeseli, iipleyiti zokukhwela iiseli, iibhotile zokukhuliswa kweeseli, njl. Ngokuqhelekileyo, izixhobo zokunyanga umphezulu weplasma zisetyenziselwa ukufezekisa unyango lwe-TC olungaphezulu kwezitya zenkcubeko yeseli.
Iimpawu zesitya senkcubeko yeseli emva konyango lomphezulu we-TC
1. Ukucoca kwangaphambili umgangatho wemveliso: I-plasma ye-O2 inokufunxa iincinci ezincinci kunye nezinye izinto ezingcolileyo eziqhotyoshelwe kumphezulu wemveliso, kwaye udwebe igesi edibeneyo ngaphandle kwegumbi lokucoca ngepompo yokucoca ukufezekisa umphumo wokucoca kwangaphambili.
2. Ukunciphisa uxinzelelo lomphezulu wemveliso, ukwenzela ukuba i-angle yoqhagamshelwano lwamanzi yemveliso iyancipha kakhulu, kwaye ihambelane ne-ionization yamandla afanelekileyo kunye noxinaniso, ukwenzela ukuba i-angle yoqhagamshelwano lwamanzi yommandla wemveliso WCA <10 °.I-3 I-plasma ye-O2 iya kusabela ngeekhemikhali kwindawo yemveliso, kwaye amaqela amaninzi asebenzayo anokongezwa kwindawo yemveliso, kuquka i-hydroxyl (- OH), i-carboxyl (- COOH), i-carbonyl (- CO -), i-hydroperoxy (- OOH), njl. La maqela asebenzayo asebenzayo anokuphucula isantya senkcubeko kunye nomsebenzi ngexesha lenkcubeko yeeseli.
