Beschreibung
Zusammenfassung:	This invention provides core shell silica particles, wherein each core shell silica particle comprises a silica core, and a surface of the silica core etched with group I metal silicate. These core shell silica particles have high surface charge density and anti-bacterial activity. Also provided are compositions comprising core shell silica particles, process of making the core shell silica particles and methods of reducing or inhibiting bacterial activity by administering the core shell silica particles or compositions thereof. La présente invention concerne des particules cur-écorce de silice, chaque particule cur-écorce de silice comprenant un cur en silice et la surface du cur en silice étant gravée au moyen d'un silicate d'un métal du groupe I. Ces particules cur-écorce de silice présentent une grande densité de charge superficielle et une intense activité antibactérienne. L'invention concerne également des compositions contenant des particules cur-écorce de silice, un procédé de fabrication desdites particules cur-écorce de silice et des procédés de réduction ou d'inhibition de l'activité bactérienne grâce à l'administration desdites particules cur-écorce de silice ou de compositions en contenant.
