Abstract
The present invention discloses methods for the processing of commercially obtained silicon carbide particles to enhance the nucleic acid binding properties of the silicon carbide. The methods use a variety of chemical washes which may also use high temperature treatment under gentle boiling followed by cooling and allowing the particles to settle, and milling to obtain the desired grit size.
