Special Issue Information

Dear Colleagues,

Recent advances in photocatalytic nanomaterials have introduced innovative materials with enhanced light absorption, charge separation, and catalytic efficiency. These achievements address critical challenges in environmental remediation, clean energy production, and sustainable chemistry. Key innovations include plasmonic hybrids, Earth-abundant cocatalysts, and biomass conversion strategies driven by structural and compositional engineering. Nanomaterials are considered the best photocatalysts due to their high stability, safety, low cost, and superior photoactivity. Photocatalysis is an environmentally friendly, cost-effective, and highly efficient approach for removing various pollutants, such as heavy metals, organic, inorganic, and microbial contaminants, in the presence of light and catalysts, and it is also a key technology for producing clean fuels.

We hope this Special Issue of Molecules will cover the recent progress in nanomaterials for photocatalysis, including the synthesis of new and improved photocatalysts using chemical, physical, and biological approaches, new applications, and the in-depth comprehension of reaction mechanisms.

Potential topics include, but are not limited to, the following:

  • The design and synthesis of nanomaterial photocatalysts with tailored optical properties.
  • Nanomaterial photocatalysts for clean fuel resources.
  • Nanomaterial photocatalysts for CO2 reduction.
  • Photocatalytic advanced oxidation/reduction processes for the degradation of environmental pollutants.
  • Studies of the photocatalysis reaction mechanism.
  • Self-cleaning surfaces using photocatalysis.
  • Factors affecting the activity of nanomaterial photocatalysts.
  • Nanomaterial photocatalysts for biological applications.

Modern medicine is facing a significant challenge in dealing with infections caused by Candida spp. and the biofilms they form. Although there are numerous treatment methods available for Candida species, standard therapeutic protocols are increasingly failing, particularly in cases of chronic local infections, such as those affecting immunocompromised patients (e.g., due to immunosuppression or diabetes). In such cases, a promising approach is to use nanomaterials to inactivate and eradicate Candida spp. and their biofilms. In order to limit the spread of Candida spp. and their biofilms within the healthcare environment, thereby reducing the risk of patient infection, photocatalysis appears to be a noteworthy method for improving therapeutic outcomes. Candida spp. biofilms are difficult to eradicate because they possess multiple resistance mechanisms—including protective extracellular matrix, efflux pumps, quorum sensing, persister and Goliath cells—which collectively enhance drug tolerance, adhesion, and survival rates under antifungal treatment. The use of nanomaterials, such as nanoparticles, carbon dots, or nanozymes for photocatalytic processes, seems to be a promising solution, showing outstanding results in Candida spp. biofilm disruption and inactivation. This is due to their superior biofilm penetration, effective destruction of proteins and enzymes, destabilization of EPS, degradation of nucleic acids, and reduced drug resistance. We collected the most important nanomaterials useful in combating Candida spp. biofilm and organized the photocatalysis mechanism of action in its disruption. Based on current research, we have compiled modern strategies involving nanomaterials and their photocatalytic activity for potential application in the healthcare environment, with the aim of reducing the presence of Candida spp. biofilms and, consequently, lowering the incidence of Candida spp.-related infections.
