Abstract

We describe the detection of specific, conserved DNA sequences of herpes simplex virus (HSV) type 1 by means of a novel, high sensitivity acoustic biosensor. Repeated assays on planar and polymeric carboxylic acid- and biotin-presenting surface chemistries enabled statistical comparison of assay specificity and sensitivity and evaluation of assayZ-factor scores. Using a three minute hybridisation with NeutrAvidin capture for signal enhancement, it was possible to detect HSV viral nucleic acids at 5.2 × 10⁻¹¹ M concentration.
