“…Titanium-, gold-, silver-, and copper-based nanoparticles have been widely analyzed for antibacterial and antibiofilm effectiveness . These metal-oxide nanoparticles enter the cell mostly via electrostatic attraction, accumulate, and lead to ROS generation causing cell membrane disruption, protein photo-oxidation, and inhibition of enzyme activity and generating superoxide radicals. − Though metal nanoparticles of gold, silver, titanium oxide, and zinc oxide have shown good antimicrobial properties, concerns about their biocompatibility , have limited their use, and carbon-based nanomaterials are being greatly explored. , After the accidental discovery of CDs in 2004, these minuscule particles have gained considerable attention because of their superior optical properties, photostability, aqueous solubility, and biocompatibility. ,− CDs are zero-dimensional quantum dots with a size below 10 nm comprising a carbon core and a surface passivation layer. The carbon in the core structure is either sp 2 or sp 3 hybridized carbon.…”

Biofilms are an intricate community of microbes that colonize solid surfaces, communicating via a quorum-sensing mechanism. These microbial aggregates secrete exopolysaccharides facilitating adhesion and conferring resistance to drugs and antimicrobial agents. The escalating global concern over biofilm-related infections on medical devices underscores the severe threat to human health. Carbon dots (CDs) have emerged as a promising substrate to combat microbes and disrupt biofilm matrices. Their numerous advantages such as facile surface functionalization and specific antimicrobial properties, position them as innovative anti-biofilm agents. Due to their minuscule size, CDs can penetrate microbial cells, inhibiting growth via cytoplasmic leakage, reactive oxygen species (ROS) generation, and genetic material fragmentation. Research has demonstrated the efficacy of CDs in inhibiting biofilms formed by key pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. Consequently, the development of CD-based coatings and hydrogels holds promise for eradicating biofilm formation, thereby enhancing treatment efficacy, reducing clinical expenses, and minimizing the need for implant revision surgeries. This review provides insights into the mechanisms of biofilm formation on implants, surveys major biofilm-forming pathogens and associated infections, and specifically highlights the anti-biofilm properties of CDs emphasizing their potential as coatings on medical implants.

“…Metallopolymer nanocomposites are hybrid nanomaterials that combine metal components’ electrical, optical, catalytic, and thermal properties with the polymer component’s flexibility, solubility, and manufacturability. − These nanomaterials have been broadly utilized in biomedical applications because of their superior properties. Silver NP–polyvinylpyrrolidone–[meglumine antimoniate (Glucantime)]) nanocomposite, abbreviated as Ag NPs-PVP-MA, exhibited considerable antileishmanial activity against Leishmania amazonensis infection in vitro.…”

Leishmaniasis, one of the most overlooked tropical diseases, is a life-threatening illness caused by the parasite Leishmania donovani that is prevalent in underdeveloped nations. Over 350 million individuals in more than 90 different nations worldwide are at risk of contracting the disease, which has a current fatality rate of 50 000 mortalities each year. The administration of liposomal Amp B, pentavalent antimonials, and miltefosine are still considered integral components of the chemotherapy regimen. Antileishmanial medications fail to treat leishmaniasis because of their numerous drawbacks. These include inadequate effectiveness, toxicity, undesired side effects, drug resistance, treatment duration, and cost. Consequently, there is a need to overcome the limitations of conventional therapeutics. Nanotechnology has demonstrated promising outcomes in addressing these issues because of its small size and distinctive characteristics, such as enhanced bioavailability, lower toxicity, biodegradability, and targeted drug delivery. This review is an effort to highlight the recent progress in various nanodrug delivery systems (nDDSs) over the past five years for treating leishmaniasis. Although the preclinical outcomes of nDDSs have shown promising treatment for leishmaniasis, further research is needed for their clinical translation. Advancement in three primary priority domains�molecular diagnostics, clinical investigation, and knowledge dissemination and standardization�is imperative to propel the leishmaniasis field toward translational outcomes.

“…Therefore, the calcium carboxylate group may be responsible for the antibacterial nature of the composite. 139 The biofilm formation component of the composite was evaluated and showed biofilm inhibition values of approximately 67% and 74% for S. aureus and E. coli, respectively. Therefore, the material can prevent the development of biofilms by pathogens.…”

Hydroxyapatite can combine with polysaccharide originating biomaterials with special applications in the biomedical field. In this review, the synthesis of (nano)composites is discussed, focusing on natural polysaccharides such as alginate, chitosan, and pectin. In this way, advances in recent years in the development of preparing materials are revised and discussed. Therefore, an overview of the recent synthesis and applications of polyssacharides@ hydroxyapatites is presented. Several studies based on chitosan@ hydroxyapatite combined with other inorganic matrices are highlighted, while pectin@hydroxyapatite is present in a smaller number of reports. Biomedical applications as drug carriers, adsorbents, and bone implants are discussed, combining their dependence with the nature of interactions on the molecular scale and the type of polysaccharides used, which is a relevant aspect to be explored.
