A system and method for processing and detecting nucleic acids from a set of biological samples, comprising: a capture plate and a capture plate module configured to facilitate binding of nucleic acids within the set of biological samples to magnetic beads; a molecular diagnostic module configured to receive nucleic acids bound to magnetic beads, isolate nucleic acids, and analyze nucleic acids, comprising a cartridge receiving module, a heating/cooling subsystem and a magnet configured to facilitate isolation of nucleic acids, a valve actuation subsystem configured to control fluid flow through a microfluidic cartridge for processing nucleic acids, and an optical subsystem for analysis of nucleic acids; a fluid handling system configured to deliver samples and reagents to components of the system to facilitate molecular diagnostic protocols; and an assay strip configured to combine nucleic acid samples with molecular diagnostic reagents for analysis of nucleic acids.

System and method for processing and detecting nucleic acids

A method for nucleic acid isolation comprising: receiving a binding moiety solution within a process chamber; mixing the binding moiety solution with a biological sample, within the process chamber, in order to produce a moiety-sample mixture; incubating the moiety-sample mixture during a time window, thereby producing a solution comprising a set of moiety-bound nucleic acid particles and a waste volume; separating the set of moiety-bound nucleic acid particles from the waste volume; washing the set of moiety-bound nucleic acid particles; and releasing a nucleic acid sample from the set of moiety-bound nucleic acid particles. The method preferably utilizes a binding moiety comprising at least one of poly(allylamine) and polypropylenimine tetramine dendrimer, both of which reversibly bind and unbind to nucleic acids based upon environmental pH.
