An antibacterial conjugate of carbon nanohorns for NIR-light mediated peri-implantitis treatment.

This study developed a novel antibacterial conjugate based on carbon nanohorns for peri-implantisis, an inflammatory disease around dental implants, which may result in failing implants by bone loss around them. The conjugate demonstrates much better photodurability than commonly used indocyanine green and a significant antibacterial effect under NIR illumination.
