Abstract

Micro and nano-patterned devices were fabricated which disclose the possibility of concentrating, localizing, detecting and thus analyzing with unprecedented accuracy few molecules (at the limit a single molecule) of biological and medical interest. Important applications are envisioned where proteins poorly concentrated in blood are detected thus (early) revealing the appearance of diseases. The major advance of the paper is that it combines micro/nano-fabrication and spectroscopical nano-optics based techniques to study and individualize the biomolecules at study. Super hydrophobic surface would concentrate the diluted solution into a small area whereas spectroscopical nano-optics techniques would gather the molecular/chemical information of the residual solute. Fluorescence and SERS techniques were used to analyze Rhodamine molecules initially highly diluted (10-18 M).
