Implication

Randomized trial evaluates antimicrobial activity of nitrogen-containing carbonaceous materials, indicating potential for sunlight-responsive applications.

Key Points

The research aimed to assess the antimicrobial performance of nitrogen-containing carbonaceous materials under visible and infrared light.
Nitrogen-containing carbonaceous materials (C2N) were synthesized via thermal decomposition of organic precursors.
Antimicrobial activity was tested by counting colony-forming units (CFU) on C2N-coated plates after light irradiation.
Comparative studies were conducted with titanium oxide and graphitic carbon nitride to establish photocatalytic contributions.
C2N materials demonstrated significant antimicrobial activity under visible and infrared light irradiation.
FTIR analysis indicated small optical band gaps of 0.55 eV and 0.47 eV, enabling low-energy light activation.
The antimicrobial effect is primarily attributed to photocatalytic processes induced by light exposure.
