This article elucidates the promise and challenges of autonomous nanomedicine, emphasizing its ability to overcome the limitations of traditional methods such as chemotherapy and radiotherapy. Central to its efficacy are nano-sized carriers, which autonomously navigate the body to deliver therapeutic agents with precision and control. By integrating automated nanoscale tools into disease detection processes, this technology offers swift and personalized assessments, reshaping disease management paradigms. To advance the clinical translation of autonomous nanomedicine, rigorous preclinical studies are imperative. However, challenges persist in ensuring reproducibility and safety, hindering progress in clinical trials. This article examines current studies with potential clinical translation, shedding light on the regulatory and ethical considerations crucial for its safe implementation. As the field progresses, maintaining a balance between innovation and safety remains paramount for harnessing the full potential of autonomous nanomedicine while safeguarding patient well-being.<h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"35 8","pages":"2607 - 2635"},"PeriodicalIF":2.7,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10876-024-02691-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, the majority of reported cyclic boron oxide structures consist predominantly of four to six-membered rings. In this study, we employ theoretical methods to predict the global-minimum (GM) structure of B6O62+. Our analyses, including global-minimum searches and calculations using B3LYP, PBE, PBE0, and single-point CCSD(T), reveal that the D2h B6O62+ (1Ag) configuration represents a planar and tricyclic structure, resulting from the fusion of B3O2/B4O2/B3O2 units. Remarkably, this structure establishes the B6O62+ cluster as the smallest boron oxide cluster with a planar tricyclic motif. Further bonding analysis indicates that B6O62+ is a weakly antiaromatic system with 12π delocalized electrons. The reported B6O6 has a planar structure with a 6-membered B3O3 ring and 6 π electrons distributed over the ring. Because of the absence of two electrons from the highest occupied molecular orbital (HOMO) of neutral B6O6, the structure of B6O62+ is distinctly different from that of B6O6.</div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"35 8","pages":"2747 - 2752"},"PeriodicalIF":2.7,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized nanocomposite was characterized XRD, FT-IR, FE-SEM, TEM, EDS, PL, UV–Vis DRS techniques. Subsequently, various parameters such as the effect of NiCo2O4 amount in the composite structure, pH, initial pollutant concentration, photocatalyst dosage, and different scavengers were investigated to determine the exact mechanism of the photocatalytic process. In different concentrations of NiCo2O4, the base value (X: 1) was determined as the optimal value in photocatalytic degradation. g-C3N4/TiO2/NiCo2O4 composite had the highest percentage of 99.5% Rh.B dye degradation in 60 min. In addition, by examining the pH, it was found that its optimal value is 7, and the rate of dye degradation in this condition is more than other materials, and the rate constant value is 0.069 min–1. In addition, the g-C3N4/TiO2/NiCo2O4 catalyst showed good performance for each reuse and retained about 82% of its initial photocatalytic activity after 5 cycles. The results indicate that photoinducd (RhB) holes play a crucial role in the photocatalytic degradation of RhB in the presence of the g-C3N4/TiO2/NiCo2O4 nanocomposite via pair Z-scheme system. In the Z-scheme system, the rapid recombination between the hole-electron pair is not observed due to the electron trapping effect of the needle-shaped NiCo2O4 structure, resulting in high photocatalytic efficiency and dye degradation. Therefore, Z-scheme systems are efficient and effective for the removal of water pollutants.</div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"35 7","pages":"2539 - 2556"},"PeriodicalIF":2.7,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The situation demands, development of rapid, convenient and easy to handle detection system for SARS-CoV-2. In this regard, the optical biosensing assay was developed using antisense oligonucleotide (ASO) conjugated Poly-l-Lysine functionalized gold nanoparticles (PLL-AuNPs) for detection of SARS-CoV-2 RNA. The negatively charged ASOs were conjugated with positively charged PLL-AuNPs by electrostatic interactions which were characterized by UV–Vis spectroscopy and Transmission Electron Microscopy (TEM). ASO-PLL-AuNPs conjugate was used to detect target SARS-CoV-2 RNA within 5–6 min from COVID-19 positive samples. In presence of target SARS-CoV-2 RNA, the DNA-RNA (ASO-RNA) hybrid structure was formed that released PLL-AuNPs which was aggregated in presence of sodium chloride (NaCl). This has rendered observable red shift in Surface Plasmon Resonance (SPR) with maximum absorbance at 660 nm and visual aggregation of PLL-AuNPs. Selectivity of ASO-PLL-AuNPs conjugate was evaluated in presence of Influenza A RNA with limit of detection 0.52 ng/µL. The obtained results were compared with qRT-PCR results for nasopharyngeal samples collected from COVID-19 positive patients and were found in good agreement with qRT-PCR results.
