However, controlling the loading efficiency and capacity, and release of therapeutics at specific disease site has remained a key challenge, particularly for toxic chemotherapeutic drugs. This work explored the effect of treatment with empty silica nanoparticles (SNPs) and a chemotherapeutic drug either together (i.e. co-treatment) or in tandem (i.e. temporally spaced) on the cell ablation ability of the drug. The study also investigated whether the efficacy of the drug in response to these treatments was dependent on the morphology of particles. SNPs of four different morphologies (solid: SSNPs, dendritic: DSNPs, mesoporous: MSNPs, and rod: RSNP) were used, while cisplatin (CisPt) served as model chemotherapeutic. The efficacy of CisPt as a function of SNPs morphology and temporal treatment strategy was tested in HeLa cells. The results indicated that the morphology of particles as well as treatment strategy (i.e. co-incubation and post treatment) had an impact on not only the cell viability but also the cell death pathways, as evidenced by varying IC50 values and the flow cytometry analysis. Interestingly, co-treatment of SNPs with CisPt resulted in an across-the-board lower IC50 value compared to when the cells were first treated with SNPs for 24 h followed by CisPt treatment and even when CisPt was loaded into the particles for most of the SNPs.</div></div>","PeriodicalId":100941,"journal":{"name":"Nano TransMed","volume":"3 ","pages":"Article 100053"},"PeriodicalIF":0.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534993","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}

Metal nanoparticles (MNPs) have been attracting attention for cancer therapy due to the many advantages they provide compared to traditional cancer treatment drug delivery systems. Specifically, gold nanoparticles (AuNPs) are potentially advantageous for clinical applications because of their biocompatibility and their application in biomedical imaging. A drawback of AuNPs is that their synthesis is typically very hazardous and produces a lot of toxic byproducts. However, the green synthesis of AuNPs overcomes this issue by using natural and biological derivatives (from microorganisms, fungi, plants, etc.). This allows for a safer and less toxic procedure, while maintaining the reliability and reproducibility of AuNP synthesis. Plant-synthesized AuNPs (PAuNPs) in particular present a greatly efficient and fast method for AuNP synthesis, due to the presence of reducing agents and capping agents in plant extracts to support the nucleation and formation of AuNPs. Herein, we review existing literature to summarize recent <em>in vitro</em> and <em>in vivo</em> developments of PAuNPs against gastric cancer. Categorization of the reviewed literature includes their physiochemical characterization, cytotoxic IC₅₀’s against gastric cancer cell lines, methods of gastric cancer cell death, and the change in relevant biomarker expressions due to PAuNP presence. A generalized gastric cancer cell death mechanism is concluded, which stems from the endocytotic uptake of PAuNPs that eventually leads to mitochondria dysfunction, nuclear fragmentation, autophagy expression alteration, apoptosis, and/or ferroptosis. Although <em>in vivo</em> developments for PAuNPs against gastric cancer are limited, studies have indicated PAuNPs’ ability to cause angiogenesis inhibition and tumor size reduction. The discussion includes comments on remaining challenges and additional work for the pre-clinical development of PAuNPs against gastric cancer.</p></div>","PeriodicalId":100941,"journal":{"name":"Nano TransMed","volume":"3 ","pages":"Article 100050"},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2790676024000219/pdfft?md5=5f109a716b523012f28e03a106eabe30&pid=1-s2.0-S2790676024000219-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142270811","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}

From the temperature dependent optical absorption data, we calculated various optical parameters for these two types of samples. The optical band gap of these samples were also estimated and discussed as per the experimental conditions. The various optical parameters calculated indicate that mutated (tumor) DNA is less stable than the normal one. From the DSC data, clear melting peaks were observed for the tumor and normal samples. Also various thermodynamic parameters like change in enthalpy (Δ<em>H</em>), entropy (Δ<em>S</em>), and specific heat (Cp) were estimated. From the thermal study, it seems that the tumor DNA is less stable. Further from the electrical or current-voltage (I-V) characteristics data, the resistance for normal DNA decreases with temperature. But for tumor sample, it show anomalous behavior (like decreasing and then increasing trend) with temperature. For electrical transport, small polaron hopping could be the possible transport mechanism in the current sample. Here from these studies, the tumor sample seems more disordered, and structural fluctuations due to the speculated structure could be the best reason for this behavior.
