Mupepa iri, pH-inductive protein-scaffold biosynthesis yechimiro-tunable crystalline goridhe nanoparticles patembiricha yekamuri yakagadzirwa.Nekunyengedza kwakapusa kweiyo reaction solution's pH, anisotropic goridhe nanoparticles anosanganisira spheres, matriangles uye macubes anogona kugadzirwa nekumisikidza ane aqueous solution ye sodium tetrachloroaurate neDolichomitriopsis diversiformis biomasses mushure mekunyudzwa mumvura ye Ultrapure Millipore husiku.Protein yemoss ine huremu hwemamorekuru hunosvika 71 kDa uye pI ye4.9 ndiyo yaive yekutanga biomolecule inobatanidzwa mu biosynthesis yegoridhe nanoparticles.Kugadziridzwa kwechipiri kwemapuroteni neCD spectrum kwaireva kuti protein yemoss inogona kuratidza masisitimu akasiyana echipiri anosanganisira coil isina kurongeka, α-helix uye yepakati conformations pakati peiyo random coil uye α-helix yekuyedza pH mhinduro.Kukura kwegoridhe nanoparticles kwakaratidza zvakare kuti puroteni yemoss ine akasiyana masisitimu yakapa template sc affold yechimiro-inodzorwa biosynthesis yegoridhe nanoparticles.Chimiro chakamanikidzwa chegoridhe nanoparticles, zvisinei, chakanyangarika mune yakabikwa moss yakatorwa.Iyo nanoparticles yegoridhe ine morphology yakagadzirwa yakabudirira kuvakwazve vachishandisa moss protein yakacheneswa kubva kune goridhe nanoparticles.Mamiriro ekuumbwa neSEM, TEM uye SAED airatidza kuti katatu uye cubic goridhe nanoparticles yaive imwechete crystalline.
