Disclosed is a modular fluorescence sensor having the following general formula: Where Fl is a fluorophore, N is a nitrogen atom, Bd1 and Bd2 are independently selected binding groups, Sp is an aliphatic spacer, and An is an anchor group for attaching the sensor to solid substrates. n=1 or 2, m=1 or 2, x is an integer, and y=1 or 2. The binding groups are capable of binding an analyte molecule to form a stable 1:1 complex. In a preferred embodiment, the Bd1 is R1-B(OH)2 and Bd2 is R2-B(OH)2. R1 and R2 are aliphatic or aromatic functional groups selected independently from each other and B is a boron atom. The present invention also provides methods of synthesizing a modular fluorescence sensor and its use in labeling solid substrates. |
