Bio-inspired synthesis of chiral silver nanoparticles in mucin glycoprotein—the natural choice

Abstract

A method of synthesizing stable chiral Ag nanoparticles inside a natural mucin glycoprotein is demonstrated. The reaction is carried out without the help of an external reducing agent, by utilizing the reducing properties of the host mucin. A chiral spectrum is detected in the visible range, indicating the formation of a new type of chiral Ag nanoparticles-containing biomaterial.

Chiral supramolecular nanoparticles: The study of chiral surface modification of silver nanoparticles by cysteine and its derivatives

“…Optical activity of such systems is mostly demonstrated on gold or silver NP modified by thiol ligands [19,20]. Supramolecular optically active assemblies of nanoparticles on suitable carriers have been also discussed in the literature [21][22][23][24][25].…”

Exceptional Acid–Base Organogelators for a Wide Variety of Organic Liquids and Their Many Applications

“…Due to the absence of colored products detected by thin-layer chromatography, the red color of the solution was presumed to result from very tiny silver particles. [27] Even when an equimolar amount of silver trifluoroacetate was added, a stable red solution could still be obtained.…”

Biomolecule-assisted synthesis of highly stable dispersions of water-soluble copper nanoparticles

“…Recently, there is an increasing attraction on the topic of synthesizing metal nanoparticles with biomolecules such as DNA, amino acid and protein to reduce or eliminate the use and generation of hazardous substances [17][18][19][20]. Biomolecules, which are the building blocks of life and perform important functions in living organisms, have been used to design and synthesize complicated nanostructures at molecular level [21].…”
