After excitation by light, a photoabsorber can emit ultrasound waves, which are in turn detected by a sound transducer. In this study, selected colon cancer HT-29 cells are research targets. PEGylated gold nanoprisms are designed and prepared with the aim to study the feasibility of using them as a novel contrast agent for the hybrid technique of optoacoustic imaging.
