Nowadays, tumor imaging is widely used in biomedical field. However, the materials of imaging is rarely and strict. This study developed a method for preparing autofluorescent polyacrylamide nanoparticles (NPs). The polyacrylamide NPs were treated with glutaraldehyde, and then removed excess glutaraldehyde through ultrafiltration, glycine neutralization and ethanol precipitation, respectively. Based on this method, the polyacrylamide NPs showed strong nearinfrared fluorescence (NIRF) at the
