Title: Nucleic acid sample purification and enrichment with a thermo-affinity microfluidic sub-circuit

Abstract

Multiplexed affinity purification and thermal dissociation prior to biochip hybridization simplifies uncharacterized sample admixtures, thereby minimizing or eliminating sample interferents, improving hybridization specificity on a microarray detector, and minimizing or eliminating the need for post-hybridization thermal dissociation analysis. An integrated thermo-affinity sample preparation sub-circuit for sample purification and enrichment is described that is consistent with a field-portable form factor and analytical processes. Thermo-affinity sample preparation on model admixtures of varying complexity was efficacious.
