一个合理设计的肽和硫代烷基化的聚（乙二醇）用于稳定银纳米粒子在水中。颗粒聚集和氧化被防止到使得纳米颗粒溶液在高浓度NaCl存在下和在宽pH范围内稳定的程度。这为银纳米颗粒在生物应用中的使用打开了大门。
A rationally designed peptide and a thioalkylated poly(ethylene glycol) are used to stabilize Ag nanoparticles in water. Particle aggregation and oxidation are prevented to such a degree that nanoparticle solutions are stable in the presence of high concentrations of NaCl and over a wide pH range. This opens the door for the use of Ag nanoparticles in biological applications.
