Surface-enhanced Raman measurements of <1 μL analyte/colloid meso-droplets on superhydrophobic wires with hydrophilic tips allowed dipicolinic acid, a spore biomarker for Bacillus anthracis (anthrax), to be detected at 10−6 mol dm−3. This is equivalent to 18 spores, significantly below the infective dose of 104 spores and 2 orders of magnitude better than previous measurements.
