Muri iyi nyandiko, hashyizweho pH-inductive protein-scaffold biosynthesis ya shusho-ihindagurika ya kristaline ya zahabu nanoparticles ku bushyuhe bwicyumba.Hifashishijwe uburyo bworoshye bwo gukemura igisubizo cya pH, nanoparticles ya zahabu ya anisotropique harimo serefe, mpandeshatu na cubes ishobora kubyara hifashishijwe igisubizo cyamazi ya sodium tetrachloroaurate hamwe na biomasses ya Dolichomitriopsis diversiformis nyuma yo kwibizwa mumazi ya ultrapure Millipore ijoro ryose.Poroteyine ya moss ifite uburemere bwa molekuline igera kuri 71 kDa na pI ya 4.9 niyo biomolecule yambere yagize uruhare muri biosynthesis ya nanoparticles ya zahabu.Ibice bya kabiri bya poroteyine byakozwe na CD byerekana ko poroteyine ya moss ishobora kwerekana ibishushanyo bya kabiri bitandukanye birimo coil idasanzwe, α-helix hamwe no guhuza hagati hagati ya coil idasanzwe na α-helix kugirango igisubizo cya pH gikemuke.Imikurire ya zahabu nanoparticles yongeye kwerekana ko poroteyine ya moss ifite ibishushanyo bitandukanye byatanze icyitegererezo sc igereranya imiterere ya biosynthesis igenzurwa na zahabu ya nanoparticles.Imiterere yabujijwe ya nanoparticles ya zahabu, ariko, yazimye mumashanyarazi yatetse.Nanoparticles ya zahabu hamwe na morphologie yabugenewe yubatswe neza hifashishijwe protein ya moss yatunganijwe muri nanoparticles.Imiterere iranga SEM, TEM na SAED yerekanaga ko nanoparticles ya mpandeshatu na cubic yari kristaline imwe.
