(a) Bright-field image and (b) red-fluorescence image after subcutaneous injection of GQDs in different areas. The excitation wavelength was 502–540 nm, and the collected fluorescence channel was 695–775 nm. (c) Photographs of mice after various treatments on the 1st, 9th, 17th and 25th day. (PDT: GQDs+light irradiation; C1: GQDs only; C2: light irradiation only.) (d) Time-dependent tumour growth curves (n=5) after different treatments. P<0.05 for each group.
