In addition, the effect of PVP K15 concentration on the formation of silver–polystyrene nanocomposite particles was investigated. On the basis of the experimental results, the effect of the PVP molecular weight and concentration on the formation of composite particles was discussed in detail. This ...
The method further requires a nontraditional silica precursor, diglycerylsilane, which efficiently undergoes sol–gel processing at neutrality. Under these conditions, higher molecular weight PVP leads to th... 展开 关键词: core-shell nanotechnology diglyceroxysilane AuNP silica shell colorimetric assay ...
When NaOH was used, the reaction rate was very fast and hence only PVP with large molecular weight could produce silver colloids of sizes around 20 nm. On the other hand, when Na 2CO 3 was used, the reaction path was significantly changed and slowed down as well. Under this circumstance...
