Carbon dots are generally used as a carrier for delivering the drug for treating diseases, which somehow reduces the toxicity of the drug and increases its activity but not that much. Our review focuses on the biogenic approach for the synthesis of carbon dots, which is also a part of green synthesis. Biogenic techniques involve the principle of using living organisms such as plants and microorganisms for the synthesis of carbon dots. The biogenic approach provides various benefits such as low toxicity, sustainable and renewable sources, eco-friendly, and some biological activity. Carbon dots prepared from the biogenic source provides biological properties such as antimicrobial, anticancer, antioxidant, anti-inflammatory, and some other biological activity, which inbuilt into carbon dots and give their therapeutic action without further drug loading. Biological or therapeutic activity containing carbon dots also minimizes drug resistance, non-target side effects into cells and drug-related adverse effects, which provides great advancement for treating the diseases.

The quest for novel methods targeting the degradation of MPs has increased in recent years. Recent studies and research, focussed on techniques like biodegradation, thermal degradation, pyrolization and nanoparticle-mediated microplastic degradation as a prominent way to overcome this issue. In the realm of emerging methodologies, metal-organic frameworks (MOFs) exhibit significant potential for MPs degradation. MOFs are highly porous 2D or 3D materials with a large surface area, adaptable chemical composition, and configurable pore size. These properties render MOFs suitable for the adsorption and degradation of MPs. The efficacy of MOF-mediated MPs degradation is dependent on the type of MOF, size, shape of MPs, and environmental conditions. They are also sustainable, efficient, and adaptable materials, making them suited for MPs degradation. This review examines diverse methodologies for the degradation of MPs, encompassing processes such as hydrolysis, oxidation, photo-degradation, bio-mimicking, phase transformation, and photoelectrochemical mechanisms. Future research prospects on the application of MOFs for MP degradation have also been addressed. MOF-mediated MP degradation is still in its infancy, but it has the potential to represent a significant advancement in this area.

We analyzed the operation of PSCs and emphasized the value of ETLs in enabling effective charge extraction and minimizing recombination losses. In<sub>2</sub>S<sub>3</sub> is a favorable nanomaterial for ETL applications due to its advantageous bandgap, excellent electron mobility, and chemical stability. Furthermore, the perovskite layer is shielded by In<sub>2</sub>S<sub>3</sub>'s passivation properties, which also increase the stability of the device. A summary of recent developments in In<sub>2</sub>S<sub>3</sub>-based ETL research, including material engineering and deposition methods improvements, has been provided. The main view for the future is the possibility of improved In<sub>2</sub>S<sub>3</sub> property optimization and interface engineering to improve PSC performance. Collaboration between scientists working on solar energy, devices, and materials will probably lead to new discoveries and test the limits of In<sub>2</sub>S<sub>3</sub>-based ETLs. Novel hybrid architectures and tandem arrangements provide exciting opportunities for better charge extraction with existing electron transport materials. The current investigation of In<sub>2</sub>S<sub>3</sub>-based ETLs in PSCs offers significant promise to revolutionize the solar energy sector, opening the path for sustainable and effective photovoltaic technology. However, stability, toxicity, and large-scale production issues must be addressed.</p></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949829524000251/pdfft?md5=fb20aaba5ae6da1fc46c8df69ac6411d&pid=1-s2.0-S2949829524000251-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140347689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
