Abstract
The present invention provides a polyol-doped aerogel material with improved properties for trapping biological particles and facilitating analysis and identification thereof. The polyol-doped aerogel material can be used in combination with a substrate by coating or otherwise depositing the material thereon. The present invention provides a method for detecting a biological particle involving use of a polyol-doped aerogel material.
Claims19
An improved biological particle capture medium, comprising:
- a polyol-doped aerogel deposited on a substrate.
An improved biological particle capture surface, comprising:
- a silica gel aerogel coating;
- and
- a glycerol dopant.
A method for bioassay, comprising the steps of:
- providing a filter comprising an aerogel and glycerol;
- placing the filter in an environment to be assayed for a period of time sufficient to expose the filter to a volume of air in the environment;
- removing the filter from the environment;
- and
- performing a test to determine the presence of a biological particle on the filter.
