摘要:
The present invention relates generally to systems and methods for processing a biological sample that result in a physical change, such as reacting two molecules together to form a reaction product or for use in lysing viruses or biological cells for analysis using biological assay systems. As such, the present invention relates both to breaking apart biological species such as viruses and cells, as well as the formation of reactants from one or more reactive species. The sample has a volume in the range from about 1 microliter to 10 milliliters. The sample is processed by applying pressure, and either sonic energy or thermal energy to the sample, wherein the pressure achieved is usually at least 24 atmospheres, and the temperature of the sample is usually raised to at least 50° C.

Provided herein are biologic sample preparation and analysis systems that are rapid, portable, robust detection system for multiplexed detection of bio-threats, and which can be ruggedized to operate in harsh environments. A new method of detection called Combinatorial Probe Analysis (CPA), which provides an exponential increase in detection reliability, has been incorporated into these systems. This type of analysis greatly reduces false positives and false negatives; in addition it is reusable and eliminates special storage requirements for reagents. Specific technical advancements in the optimization of hybridization assays for nucleic acid detection on porous polymer monoliths (PPM) are also disclosed. Performing rapid and complete solubilization of viruses, vegetative bacteria and bacterial spores with an ultra high temperature solubilization protocol is also described. The systems provided herein provides the ability to perform rapid highly multiplexed analysis of a variety of bioagents, including bacteria viruses, and protein biotoxins. The systems and assays described herein are perform completely automated sample preparation and analysis, in a time frame of five minutes or less. The assay is simple in design allowing users in personal protective equipment to easily operate the system. The disclosed systems are robust, simple to use, and address the goals of the first responder community.
