This invention generally relates to nanocrystal compounds, and linker arm for nanocrystal compounds that attach the nanocrystals to the organic compounds. The nanocrystal compound comprises a nanocrystal, linker arm, and organic compound. Preferably, the organic compound is a biologically active compound that can provide a fluorescent sensor. Preferably, the linker arm is a polyether chain with an attachment point for the nanocrystal and an attachment point for the organic compound. Specifically, the nanocrystal is attached to the linker arm through a R group and the organic compound is attached to the linker arm through a R2 group.R is a bond or is selected from the group consisting of: SH, O(CH2(n)O)nSH, NH(CH2(n)O)nSH, NH(CH2(n)NH)SH, S(CH2(n)O)nSH, and S(CH2(n)S)SH. n is 1-10, with S being attached to the nanocrystal. R2 is a bond or selected from the group consisting of carbonyl, NH, S, CONH, COO, S, C1-10 alkyl, carbamate, and thiocarbamate. |
