Lesi sihloko sibika ukusetshenziswa kwe-atmospheric pressure plasma processing ukuze kufakwe amakhemikhali e-poly(ethylene glycol) methyl ether methacrylate (PEGMA) endaweni ye-polystyrene (PS) kanye ne-poly(methyl methacrylate) (PMMA) ngenhloso yokuthola ukuhambisana kwe-adlayer okuyiyo. imelana ne-protein adsorption.Ukwelashwa kwe-plasma kwenziwa kusetshenziswa i-dielectric barrier discharge (DBD) reactor ene-PEGMA yezisindo zamangqamuzana (MW) 1000 no-2000, i-PEGMA(1000) kanye ne-PEGMA(2000), ixhunywe ngenqubo yezinyathelo ezimbili: (1) amaqembu asebenzayo. akhiqizwa endaweni ye-polymer elandelwa (2) ukusabela okungeziwe kwe-radical ne-PEGMA.Ikhemistri engaphezulu, ukubumbana, kanye nesimo sezulu sezindawo ezixhunyelelwe ze-PEGMA eziwumphumela zazibonakala nge-X-ray photoelectron spectroscopy (XPS), i-ion mass spectrometry yesikhathi sokundiza (ToF-SIMS), kanye ne-atomic force microscopy (AFM), ngokulandelanayo. .Izingqimba ze-PEGMA ezixhunyelelwe ngokuhambisana kakhulu zaqashelwa i-macromolecule ye-PEGMA engu-2000 MW, i-DBD ecutshungulwe ngethamo lamandla elingu-105.0 J/cm(2) njengoba kuboniswa izithombe ze-ToF-SIMS.Umthelela wesendlalelo se-chemisorbed PEGMA ekukhangisweni kwamaprotheni uye wahlolwa ngokuhlola impendulo engaphezulu ku-albumin ye-bovine serum (BSA) kusetshenziswa i-XPS.I-BSA isetshenziswe njengephrotheni eyimodeli ukuze kunqunywe ukuhlanganiswa kwe-macromolecular okuxhunyelelwe kongqimba lwe-PEGMA.Nakuba izindawo ze-PEGMA(1000) zibonise ukukhangiswa kwamaprotheni athile, izindawo ze-PEGMA(2000) zibonakale zimunca inani elilinganiselwe leprotheyini, okuqinisekisa ukuhlangana okuphezulu kwendawo yendawo engangcolisiwe.
