Abstract
A device for detecting biospecific oligonucleotides includes a plurality of microgel spots, each of which is functionalized with molecular beacon probes and amplification primers tethered thereto. Each of the respective probes is arranged to bind to an antisense counterpart of one type of biospecific oligonucleotide. The various microgels may each be functionalized for a different oligonucleotide. In a system that incorporates the aforesaid device, the device is in contact with a solution that includes a system of molecules that cooperated with the tethered probes and primers to capture, amplify, and detect the antisense counterparts of one or more biospecific oligonucleotides. In one such system, the enzymes and primers are arranged to implement a NASBA amplification process operating on the biospecific oligonucleotides.
