Research Progress on Bismuth-based Antibacterial Nanomaterials
Bismuth(Bi),as a heavy metal of low toxicity,has been used to synthesize various nanomaterials with unique structure and physical and chemical properties.The synthesized bismuth-based nanomaterials have the characteristics of good biocompatibility,a favorably high X-ray attenuation coefficient,a long circulation half-life,high stability,excellent light-to-heat conversion efficiency and photocatalytic ability.Due to these properties,bismuth-based nanomaterials are widely used in biomedical fields such as tissue engineering,antibacterial materials and anti-cancer treatment.It is reported that bismuth-based nanomaterials have been made into drugs for the treatment of diseases.Compared with traditional antibacterial drugs,bismuth-based nanomaterials as antibacterial agents can effectively avoid the occurrence of bacterial drug resistance.The properties,antibacterial mechanism and progress in the antibacterial field of bismuth-based nanomaterials are reviewed.Furthermore,the future research direction of bismuth-based antibacterial nanomaterials is proposed.
