Small water-soluble quantum dots |
| 摘要 |
Water-soluble, stable fluorescent PEGylated alkanethiol-coated quantum dots are made by contacting quantum dots with PEGylated alkanethiol in a non-oxidative, water-immiscible organic reaction solvent under a non-oxidative gas, wherein the reaction solvent is in contact with an aqueous phase, at elevated temperature and time sufficient to coat the dots with the PEGylated alkanethiol, wherein resultant water-soluble, stable fluorescent PEGylated alkanethiol-coated dots enter the aqueous phase. |

1. A method of making water-soluble, stable fluorescent PEGylated alkanethiol-coated quantum dots, the method comprising:
contacting quantum dots with PEGylated alkanethiol in a non-oxidative, water-immiscible organic reaction solvent under a non-oxidative gas, wherein the reaction solvent is in contact with an aqueous phase, at elevated temperature of 40-80° C. and time sufficient to coat the dots with the PEGylated alkanethiol, wherein resultant water-soluble, stable fluorescent PEGylated alkanethiol-coated dots enter the aqueous phase, wherein the PEGylated alkanethiol is in a mixture of the PEGylated alkanethiol and functionalized PEGylated alkanethiol. |
