Warqadan, pH-inductive protein-scaffold biosynthesis of nanoparticles dahab crystalline qaab-la jaanqaadi kara heerkulka qolka ayaa la sameeyay.Iyada oo si fudud loogu dhaqmo pH-ga jawaabta falcelinta, nanoparticles dahab anisotropic ah oo ay ku jiraan spheres, saddex xagal iyo xabadaha ayaa la soo saari karaa iyada oo la dhex gelinayo xal biyo ah oo sodium tetrachloroaurate ah oo leh Dolichomitriopsis diversiformis biomasses ka dib markii la geliyo biyaha ultrapure Milpore habeen.Barootiin moss ah oo miisaankiisu yahay 71 kDa iyo pI ee 4.9 ayaa ahaa biomolecule aasaasiga ah ee ku lug leh biosynthesis ee nanoparticles dahab ah.Qaabeynta labaad ee borotiinnada ee CD spectrum waxay si maldahan u tahay in borotiinka mossku uu soo bandhigi karo qaabayn sare oo kala duwan oo ay ku jiraan gariiradda random, α-helix iyo isfaham dhexdhexaad ah oo u dhexeeya gariiradda random iyo α-helix ee xalka tijaabada pH.Geedi socodka kobaca ee nanoparticles dahabka ayaa sii muujiyay in borotiinka ajada leh qaabab kala duwan ay siiyeen template sc affold ee biosynthesis qaab-control ee nanoparticles dahab ah.Qaabka xaddidan ee nanoparticles dahabka ah, si kastaba ha ahaatee, wuxuu ku dhex lumay xashiishka la kariyey.Nanoparticles dahabka ah oo leh qaab-dhismeedka qaabaysan ayaa si guul leh dib loogu dhisay iyadoo la isticmaalayo borotiinka moss-ka ee laga sifeeyay nanoparticles dahabka ah.Tilmaamaha qaabdhismeedka ee SEM, TEM iyo SAED waxay muujiyeen in nanoparticles dahab saddex-xagal ah iyo cubic ay ahaayeen hal crystalline.
