The destructive effect of infectious diseases on human life and the emergence of antibiotic-resistant strains highlight the importance of developing new and appropriate treatment strategies, one of which is the use of metals as therapeutic agents. Bismuth nanoparticles are an example of prominent metal-containing drugs. The therapeutic effects of bismuth-based drugs in the treatment of wounds have been proven. Various laboratory studies have confirmed the antimicrobial effects of bismuth nanoparticles, including the clinical treatment of ulcers caused by . Therefore, considering the performance of this nanoparticle and its potent effect on infectious agents and its therapeutic dimensions, the present study fully investigated the properties and performance of this metal-based nanoparticle.

Bimetallic Bi-Pt nanoclusters exhibit diverse structural motifs, including core-shell, Janus, and mixed alloy configurations, due to the unique bonding characteristics between Bi and Pt atoms. Using density functional theory refinements from ChIMES physically machine-learned potential and CALYPSO particle swarm optimization global searches, 34 Bi20-Pt20 nanoclusters are systematically classified. The results reveal that Bi atoms predominantly occupy surface sites, driven by charge transfer effects.

Controlled drug delivery has attracted significant attention because of its ability to release therapeutic agents at specific times and locations. Titanium dioxide nanotubes (TNTs), which are known for their unique tubular morphology, large surface area and excellent biocompatibility, have been widely investigated as drug carriers. However, their application in light-induced drug release is limited by their reliance on ultraviolet (UV) light.

Bismuth's unique properties have led to its widespread use in medical, cosmetic, and electronic applications. However, increasing evidence suggests potential toxicity, particularly from nanoparticle forms that may accumulate in organs. This study investigated the nephrotoxic effects of bismuth oxide nanoparticles (Bi₂O₃ NPs) in male NMRI mice, focusing on underlying molecular mechanisms.

Bacterial wounds are currently a growing concern in clinical practice, with the rising challenge posed by antibiotic resistance and inflammation. Traditional photothermal therapy (PTT) presents great efficiency in treating infected wounds; however, it has the limitation of thermal damage to healthy tissues. To overcome this challenge, the strategy of mild-PTT is proposed using hyaluronic acid-coated bismuth sulfide (BiS) nanoparticles (BiH NPs) alongside allantoin within gelatin/sodium alginate-based hydrogel formulation to eliminate bacterial infections and facilitate the wound healing procedure.

Bismuth is an inexpensive, biocompatible, and semimetallic material. Light absorption in bismuth occurs by means of intraband transitions from mid-IR to UV due to its exotic electronic structure. Thus, bismuth has been pointed out as an excellent material in applications relying on optical absorption, such as computed tomography, photocatalysis, and photothermal therapy.
