Latest Patents
Nan Dai holds a patent for "Strongly quenching oligomeric excimer/quencher pairs for detection schemes." This patent describes compositions and systems designed for the high-efficiency quenching of small water-soluble oligomers, or oligofluors, ranging from about 1-10 kDa in size. The oligofluors consist of multiple excimeric or exciplex-forming fluorophores arranged on a scaffold, which are effectively quenched by a quencher entity linked to the oligomer through a cleavable moiety. The fluorophores of interest include aromatic fluorophores such as pyrenes, including benzopyrene and perylene. The oligofluor/quencher combination can achieve a Stern-Vollmer constant (K) of greater than about 10M, indicating its high efficiency. In some embodiments, the scaffold is a phosphodiester/glycoside backbone, which can be an analog of a polynucleotide. This innovative system can be utilized in qualitative and quantitative screening and detection methods to identify any enzymatic, chemical, or catalytic activity that can cleave the moiety between the quencher and scaffold.
