摘要： The invention provides a method for activation of aqueous dispersions of silver nanoparticles for purposes of surface enhanced Raman spectroscopy, wherein a solution of chloride ions is added to the aqueous dispersion of silver nanoparticles in the presence of oxygen in such an amount that the final chloride ion concentration in the activated dispersion ranges from 0.1 mol.dm- 3 to 1 mol.dm- 3 . Preferably, oxygen is added to the dispersion in the course of activation. This method leads to recrystallization of silver particles, which is faster and more reproducible for the purposes of surface enhanced Raman spectroscopy than the particle aggregation so far known in the art.˙
摘要翻译：本发明提供一种激活银纳米颗粒的水性分散体的方法，用于表面增强拉曼光谱，其中在氧存在下将氯离子溶液加入到银纳米颗粒的水分散体中，使得最终氯离子活化分散体中的浓度范围为0.1mol.dm-3至1mol.dm-3。优选地，在活化过程中向分散体中加入氧。这种方法导致银颗粒的再结晶，与现有技术中已知的颗粒聚集相比，为了表面增强拉曼光谱的目的，银颗粒更快，更可再现。

摘要： The invention provides a preparation containing an antibiotic, with the exclusion of β-lactam antibiotics, and silver in the form selected from nano- or microparticles and silver compound, for use in the treatment of infections caused by bacteria resistant against the antibiotic. It further provides use of this preparation for the treatment of surfaces and/or material against resistant bacteria. The invention further includes an antibiotic preparation containing a mixture of an antibiotic, with the exclusion of β-lactam antibiotics, and silver nano- or microparticles, without a chemical bond between the antibiotic and silver. The present preparations are useful in particular in human or veterinary medicine, medical tools and materials, or in cosmetics to eliminate bacterial infections caused by classical antibiotic-resistant bacteria. ˙
