Bioweapon-detecting fibrous-network products and methods for making same

摘要

Methods are disclosed for producing a bioweapon-sensitive fibrous-network product, wherein the subject products exhibit a color change in response to exposure to a biological agent (or portion thereof) as used in a biological weapon. Also disclosed are fibrous-network products that contain units of biopolymeric material that impart a color change to the products in response to exposure to a biological agent (or portion thereof) as used in a biological weapon.

主权项

1. A method for producing a biological-weapon-sensing fibrous-network product, comprising the steps:
adding units of a biological-weapon-sensing agent encapsulated in a sol-gel to a suspension of fibers suitable for making a fibrous-network product; mixing the units of the biological-weapon-sensing agent with the fiber suspension to form a mixture; and forming the mixture into a fibrous-network product comprising the fibers and the units of biological-weapon-sensing agent intermingled with the fibers through at least a part of a thickness dimension of the fibrous-network product, thereby producing the biological-weapon-sensing fibrous-network product, wherein the fibers in the suspension include noncellulosic fibers.
