Abstract: The present invention provides devices and methods for detecting and capturing molecular biomarkers from a subject in situ. Specifically, the devices contain an array of microneedles to which are attached probes specific for one or more biomarkers of interest. The devices can be used directly on a subject (e.g., via skin piercing) in detecting the biomarkers in the body of the subject (e.g., tissues, blood stream).

Abstract: A fluorescent dye-doped crystalline assay is employed for selection and detection of thiophilic heavy metal ions. While comparable in analytical performance to known solution based methodologies, the formation of crystalline analytes provides for signal amplification, and consequently, a powerful platform whose analysis is directly amenable to high-throughput video capture systems. In a microcapillary format, this assay is capable of screening hundreds of samples per day for the presence of subnanomolar concentrations of Hg2+ using a conventional fluorescence microscope.
