Abstract
Guanidine-functionalized particles and methods of making and using such particles are provided, such as guanidine-functionalized metal silicate particles. A nonwoven article is also provided including a porous fibrous nonwoven matrix and guanidine-functionalized metal silicate particles enmeshed within the porous fibrous nonwoven matrix. The nonwoven article may be used, for instance, for removing microorganisms from an aqueous sample by contacting a fluid sample with the nonwoven article such that at least a portion of the microorganisms are removed from the fluid sample.
