Abstract
A photocatalyst can be regenerated with increasing efficiency, turnover number and turnover frequency in the presence of air by irradiating the photocatalyst with a first range of wavelengths of light that excite the photocatalyst to an intermediate and irradiating the intermediate with a second range of wavelengths of light that turns the intermediate to the photocatalyst.
Claims20
A method of regenerating a photocatalyst comprising:
- irradiating the photocatalyst with a first range of wavelengths of light that excite the photocatalyst to one or more intermediates;
- and
- irradiating the one or more intermediates with a second range of wavelengths of light that turns the intermediate to the photocatalyst.
A method of diagnosing a disease comprising:
- preparing a solution including a monomer and a photocatalyst in a medium;
- adding a body fluid to the solution;
- irradiating the solution with a first range of wavelengths of light that excite the photocatalyst to one or more intermediates;
- irradiating the solution with a second range of wavelengths of light that turns the one or more intermediates to the photocatalyst;
- and
- diagnosing a disease if the monomer polymerizes.
3 more elements
A method of fluorescence imaging comprising:
- exposing a sample with a fluorophore dye with a first range of wavelengths of light that excite the photocatalyst to one or more intermediates;
- and
- exposing the sample with a second range of wavelengths of light that turns the one or more intermediates to the photocatalyst.
