Nanomaterials for the Photothermal Killing of Bacteria

Abstract: An upsurge in the multidrug-resistant (MDR) bacterial pestilence is a global cause for concern in terms of human health. Lately, nanomaterials with photothermal effects have assisted in the efficient killing of MDR bacteria, attributable to their uncommon plasmonic, photocatalytic, and structural properties. Examinations of substantial amounts of photothermally enabled nanomaterials have shown bactericidal effects in an optimized time under near-infrared (NIR) light irradiation. In this review, we have compile… Show more

“…Experimental work is currently ongoing using gold nanoparticles able to be heated as nanosources of heat when they are illuminated with a specific wavelength. This methodology can be used to kill tumoral cells [62] , [63] , [64] by transferring heat to target cells, as well as to inactivate bacteria [65] and virus ( e.g. SARS-CoV-2).…”

“…To improve the treatment efficacy, strategies include increasing the irradiation time and adding bioactive agents for co-therapy. Photothermal antibacterial materials can be combined with various antibacterial substances, (such as Cu 2 O [ 98 ], Ag + [ 99 , 100 ], and Au [ 101 ]), to increase antibacterial effect. The antimicrobial metal ions and metal oxides can act synergistically with photothermal materials to increase the antimicrobial properties of the composite material.…”

“…Nanomedicine provides nanomaterials that can be used as a substrate for cell growth and proliferation and can deliver medicine and biological molecules, which eventually results in new tissue or organ replacing the damaged body part under controlled conditions [ 104 ]. Among the various nanomedicine techniques is the guided regeneration technique, where synthetic biodegradable nanoplatforms like poly(L-lactic acid) (PLLA), polyglycolic acid (PGA), poly(D,L-lactide-co-glycolide) (PLGA), polycaprolactone (PCL), polyphosphazenes, etc., are used for directing cell growth [ 105 , 106 , 107 , 108 , 109 ].…”
