Recently, dermal infections caused by fungus have increased drastically, affecting people’s daily lives and causing embarrassment. These infections are either due to dermatophytes or non-dermatophytic fungi. Basically, three genera of dermatophytes namely Trichophyton, Microsporum and Epidermohyton are the main cause of dermatophytosis. Candida albicans is also responsible for some dermal infections as a non-dermatophytic fungus. Traditional antifungal compounds cause side effects and resistance in fungi, so better and non-toxic alternatives are needed. Now a day’s, nanotechnology is widely used in the pharmaceutical field and has proven to be a good antifungal agent. This study used TiO2 nanoparticles (NPs) against four human pathogens Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum gypseum, and Candida albicans. Green and chemical synthesis methods were used for the synthesis of TiO2 nanoparticles. In green synthesis, we used aqueous leaf extract of Pogostemon cablin Benth. The formation of TiO2 nanoparticles is confirmed by UV-visible spectroscopy, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Fourier Transform Infrared (FTIR) and X-ray Diffraction (XRD) analysis. According to XRD, the average size of chemically synthesized nanoparticles was 70.52 nm, while green synthesized nanoparticles were 71.82 nm. All the characterizations support that Pogostemon cablin aqueous extract can synthesize TiO2 nanoparticles. The minimum inhibitory concentration was determined according to the broth microdilution recommended assay. This study concluded that green synthesized TiO2 NPs showed good results against all four pathogens.

Nanotechnology (NT) and nanoparticles (NPs) have left a huge impact on every field of science today, but they have shown tremendous importance in the fields of cosmetics and environmental cleanup. NPs with photocatalytic effects have shown positive responses in wastewater treatment, cosmetics, and the biomedical field. The chemically synthesized TiO2 nanoparticles (TiO2 NPs) utilize hazardous chemicals to obtain the desired-shaped TiO2. So, microbial-based synthesis of TiO2 NPs has gained popularity due to its eco-friendly nature, biocompatibility, etc. Being NPs, TiO2 NPs have a high surface area-to-volume ratio in addition to their photocatalytic degradation nature. In the present review, the authors have emphasized the microbial (algae, bacterial, fungi, and virus-mediated) synthesis of TiO2 NPs. Furthermore, authors have exhibited the importance of TiO2 NPs in the food sector, automobile, aerospace, medical, and environmental cleanup.

“…The TiO 2 NPs' crystalline structure, functional groups (phycomolecules), particle morphology (cubic, square, and spherical), size (50-90 nm), and surface charge (negative) were examined and validated by several characterization analyses. In addition, green titanium dioxide nanoparticles were synthesized by Vasanth et al [78] using Spirulina platensis algae extract. The results showed that the absorbance spectra of the produced NPs were seen at 300 nm.…”

The use of algae-based green synthesis of metal oxide nanoparticles (MONPs) for bioremediation is an environmentally friendly and cost-effective alternative to conventional approaches. Algal-mediated synthesis offers several benefits over other biogenic processes, such as plants, bacteria, and fungi, including ease of synthesis, scalability, and rapid synthesis. Algae are readily available in nature, nontoxic, and can produce various types of metal oxide nanoparticles. This approach could significantly accelerate the development of novel algae-nanomaterials with improved properties and performance, leading to more efficient and cost-effective bioremediation of pollutants from water solutions, seawater, and industrial effluent. This review focuses on the biogenic fabrication of metal oxide nanoparticles based on aquatic plants (microalgae and seaweeds) due to their many advantages and attractive applications in pollutant remediation from aqueous solutions. Additionally, photocatalysis is highlighted as a promising tool for the remediation of industrial effluents due to its efficacy, ease of use, quick oxidation, cost-effectiveness, and reduced synthesis of harmful byproducts.
