As a firm, LED Radiofluidics is structured around developing an apparatus to allow direct or easy conversion of small molecule drug candidates to positron emission tomography (PET) agents via radiofluorination with a readily accessible, and inexpensive LED light source. PET is a powerful, rapidly developing technology playing a key role in medical imaging, as well as drug discovery and development. Despite the exceptional promise, the availability of novel PET agents is limited due to the lack of efficient and simple labeling methods to modify biologically active small molecules/drugs. Many small molecule pharmaceuticals and therapeutics contain aromatic or heteroaromatic systems within their framework; thus, it would be highly desirable for radiolabels to be introduced to this common organic subunit easily and efficiently.
