Magnetic nanowires decorated with BODIPY fluorescent dyes as highly detectable optical probes

Abstract

Our research group has developed a simple and low-cost laser scattering technique to detect magnetic nanowires in suspension in the nanograms per milliliter range. This detection level is equivalent or even better than the performance of much more complex and expensive techniques used to detect magnetic particles. In this work, we propose to enhance the sensitivity of our method by using nanowires decorated with borondipyrromethene (BODIPY) fluorescent molecules. The fluorescence will make possible to discard light scattered by non-target sources, which will greatly enhance the detection threshold. This enhancement of our robust technology will potentially lead to state-of-art technology for nanotag detection.
