System and method for detection, identification and monitoring of submicron-sized particles

Abstract

A system and method for detection, identification, and monitoring of submicron sized particles, the method including the steps of collecting a sample, extracting existing submicron particles from the collected sample based on density, purifying the extracted submicron particles by concentrating the extracted submicron particles based on size, and, detecting and identifying the purified extracted submicron particles based on size and density thereby determining submicron particles present in the collected sample. The submicron particles detected and identified include viruses and virus-like agents such as prions. Thus, virus and virus-like agents can be detected and identified based only on their physical properties without the use of biochemical reagents or assays. A system for carrying out the method of detection and identification of these particles is also disclosed.
