Abstract: A biodegradable bait station is disclosed that can be used with liquid baits targeting pest ants in urban, agricultural, and natural setting, which can overcome several limitations that most of other liquid bait stations currently experience. For example, instead of keeping a large quantity of liquid bait in a reservoir, a small amount, for example, 10-20 ml of sugary liquid bait with an insecticide, for example, boric acid, thiamethoxam, imidacloprid, will be contained in a biodegradable cylindrical container with one open end. The open end will be plugged with a piece of water absorbent polymer or gel, for example, polyacrylamide gel, sodium alginate. The water absorbent polymer or gel absorbs the liquid bait and expands inside of the cylindrical container so that it will function as a polymer “wick” to deliver a small amount of the liquid bait to foraging ants.

Abstract: A biodegradable hydrogel is disclosed for delivering aqueous bait to control pest ants. The biodegradable hydrogel includes a natural polymer of alginate cross-linked with calcium ions. A method of forming a biodegradable hydrogel is disclosed for delivering aqueous bait to control pest ants, the method includes ionotropically cross-linking sodium alginate with calcium ions.

Abstract: A method of co-functionalizing single-walled carbon nanotubes for gas sensors, which includes the steps of: fabricating single-walled carbon nanotube interconnects; synthesizing tin oxide onto the single-walled carbon nanotube interconnects; and synthesizing metal nanoparticles onto the tin oxide coated single-walled carbon nanotube interconnects.

Abstract: Conducting polymer nanowires can be doped with analyte-binding species to create a nanowire that has a different conductivity depending on the presence or absence of the analyte.
