A system for detecting a wide range of microbial organisms, including virus, and determining concentrations in near real-time to determine titer, without the requirement to grow micro-organisms includes an electrometer configured to measure photo-induced interfacial voltages and an electrode assembly with a substrate and at least one electrode on a surface of the substrate electrically coupled to the electrometer. An attachment factor is applied to an exposed surface of each electrode. The attachment factor is effective for interaction with the microbial organism. A transparent vessel for containing the electrolytic solution is provided. The microbial organism may be contained in the electrolytic solution or applied to the coated electrode before being submerged in the electrolytic solution. A light source is configured to controllably produce a flash of activating light directed through the transparent vessel at the electrode causing a sensible photo-induce interfacial voltage indicative of the microbial organism and titer. A corresponding method includes steps of preparing the electrode surfaces with an attachment factor and exposing the submerged electrode surfaces to a flash of activating light to induce interfacial voltages indicative of a determined microbial agent and titer.

Sensing device and method for rapidly determining concentrations of microbial organisms using interfacial photo-voltages

A method of controlling or eradicating mosquito populations in aqueous environments, the method comprising the creation of an aqueous environment having greater than about 2% of sugars such as dextrose, sucrose and fructose in varying ratios. Mosquito larvae fail to develop beyond the second instar stage in solutions of approximately 2% or more, and the time period for the larval stage is prolonged beyond the naturally occurring larval stage time period. Pupation and development into adulthood is reduced in solutions of lesser concentration.
