1-39. (canceled)
A method for removing diseased or damaged tissue in a subject, comprising
- (a) administering a pH-triggered polypeptide fluorophore composition comprising the structure:
- to the subject;
- (b) contacting the subject with electromagnetic radiation comprising an excitation wavelength of the fluorophore;
- (c) detecting electromagnetic radiation emitted from the composition, wherein detection of the radiation indicates the presence of the diseased or damaged tissue;
- and
- (d) surgically removing the diseased or damaged tissue identified by step (c).

54-56. (canceled)
A method for removing diseased or damaged tissue in a subject, comprising:
- (a) contacting a biological sample from a subject ex vivo with a pH-triggered polypeptide fluorophore composition comprising the structure:
- (b) contacting the biological sample with electromagnetic radiation comprising an excitation wavelength of the fluorophore;
- and
- (c) detecting electromagnetic radiation emitted from the fluorophore, wherein detection of the radiation indicates the presence of the diseased or damaged tissue;
- and
- (d) optionally, surgically removing the diseased or damaged tissue identified by step (c) from the subject.
