Black Phosphorus is an inorganic two-dimensional material whose high carrier mobility is promising for application in electronics. However, recent studies has developed biomedical use of black phosphorus by means of its high photothermal conversion property under near infrared (NIR) range excitation. Furthermore, black phosphorus oxidizes rapidly when contacted with oxygen and decomposes by water. Black Phosphorus degrades to non-toxic phosphate, phosphite, and other PxOy in the aqueous solution. This is an attractive property when low toxicity is the priority of nanomaterials in biomedicine. Here, we conducted experiment on black phosphorus exposed to 808 nm laser to confirm its photothermal effect and biodegradability. Photothermal effect of black phosphorous with different concentration and biodegradability of black phosphorous in different solvents were measured. |
