In this study, we explore nanobiohybrids, the bacterium-targeted cancer treatment approach that presents a new category of therapeutic carriers for treating cancer. We specifically focus on bacteriomimetics, where bacteria are used as natural carriers for therapeutic agents. These bacteria possess the ability of pathotropism in localizing themselves around tumor tissues, even hypoxic areas that are generally refractory to standard therapies. By engineering the surface of these bacteria, we enhance how they target tumor cells so that treatment is delivered specifically to the tumor microenvironment with no or minimal systemic side effects. Furthermore, these synthetic nanoparticles inculcated into these bacterial systems stabilize drugs and also provide a way for controlled release, which is important to maintain therapeutic effectiveness. Our results established that such nanobiohybrids are capable of efficient delivery of chemotherapeutic agents and of conducting a local real-time therapeutic response from the perspective of personalized cancer treatment. This research implies a huge development in targeted therapy against cancer, and further work has focused on optimizing these biohybrid systems for clinical applications.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":"37 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, adopting a variety of nanotechnologies will offer benefits in energy cost, computational speed, reduced footprint, cyber resilience, and processing power. The time is ripe for a roadmap for unconventional computing with nanotechnologies to guide future research, and this collection aims to fill that need. The authors provide a comprehensive roadmap for neuromorphic computing using electron spins, memristive devices, two-dimensional nanomaterials, nanomagnets, and various dynamical systems. They also address other paradigms such as Ising machines, Bayesian inference engines, probabilistic computing with p-bits, processing in memory, quantum memories and algorithms, computing with skyrmions and spin waves, and brain-inspired computing for incremental learning and problem-solving in severely resource-constrained environments. These approaches have advantages over traditional Boolean computing based on von Neumann architecture. As the computational requirements for artificial intelligence grow 50 times faster than Moore’s Law for electronics, more unconventional approaches to computing and signal processing will appear on the horizon, and this roadmap will help identify future needs and challenges. In a very fertile field, experts in the field aim to present some of the dominant and most promising technologies for unconventional computing that will be around for some time to come.

In the nanocomposite catalysts, CODs can act as modifiers to modulate the electronic properties of the metals or produce synergy with the metals. Consequently, the nanocomposite catalysts have good catalytic performance. This paper summarizes the preparation methods of nanocomposite catalysts and focuses on their applications in heterogeneous catalysis. Various specific preparation methods are not only summarized as completely as possible but also are also classified at the macro logic level. The applications of the nanocomposite catalysts in heterogeneous catalysis include photocatalysis, sonocatalysis, electrocatalysis, and thermal catalysis. It also reveals how the nanocomposite catalysts produce excellent catalytic performances in various catalytic reactions. Finally, the existing problems and the direction of future efforts are proposed. It is hoped that this paper will provide a slight reference for the future research of metal nanoparticles-carbon quantum dots nanocomposite catalysts and their application in the field of catalysis.

The major risk factors responsible for its development include age, H. pylori infection, excessive salt intake, and lack of fruits and vegetables in the diet. It is diagnosed using ultrasound, CT scan, endoscopic biopsy, and by detection of certain biomarkers. The conventional therapies for treatment of gastric cancer include the use of radiations, surgical resection, and chemotherapy. However, there are certain major issues associated with these treatments, like high risk of tumour reoccurrence, drug resistance development, less bioavailability of the drug at target site, rapid drug metabolism and high systemic toxicity due to drug doses. All such limitations of conventional treatments can be overcome with the use of herbal bio-actives as they exhibit less toxicity to normal healthy cells and reduce the risk of tumour recurrence and resistance development. Nano-formulations are developed to aid in targeted drug delivery, and to enhance the solubility, stability, bioavailability, and therapeutic efficacy of phytoconstituents. With the emergence of nanomaterials, different imaging modalities have been integrated into one single platform, and combined therapies with synergetic effects against gastric cancer were established. Moreover, the development of theragnostic strategies with simultaneous diagnostic and therapeutic ability was boosted by multifunctional nanoparticles. The present review discusses about the gastric cancer including its mortality rate, secular trends, pathophysiology, etiology, risk factors, diagnosis, and different treatment approaches with major emphasis on herbal bioactives (quercetin, paclitaxel, resveratrol, curcumin and ginsenosides) and different herbal constituent encapsulated nano-formulations (such as nanoparticles, niosomes, liposomes, nano-emulsion, and micelles).

A single layer of different 2D materials or a few layers of the same material may not always have the desired application-specific properties to an optimal level. In this context, a new trend has started gaining prominence lately to develop engineered nano-heterostructures by algorithmically stacking multiple layers of single or different 2D materials, wherein each layer could further have individual twisting angles. The enormous possibilities of forming heterostructures through combining a large number of 2D materials with different numbers, stacking sequences and twisting angles have expanded the scope of nano-scale design well beyond considering only a 2D material mono-layer with a specific set of given properties. Magic angle twisted bilayer graphene (BLG), a functional variant of van der Waals heterostructures, has created a buzz recently since it achieves unconventional superconductivity and Mott insulation at around 1.1∘ twist angle. These findings have ignited the interest of researchers to explore a whole new family of 2D heterostructures by introducing twists between layers to tune and enhance various multi-physical properties individually as well as their weighted compound goals. Here we aim to abridge outcomes of the relevant literature concerning twist-dependent physical properties of BLG and other multi-layered heterostructures, and subsequently highlight their broad-spectrum potential in critical engineering applications. The evolving trends and challenges have been critically analysed along with insightful perspectives on the potential direction of future research.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48877500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the realm of sensors, microfluidics technology enables the analysis of a small quantity of samples by facilitating the use of a minimum amount of sensor materials. Moreover, the capacity to scrutinise a diminutive sample volume result in a sensor that exhibits prompt responsiveness.

A double-emulsion solvent evaporation method was used for encapsulation of DOX and antigens into PCL NPs. The physicochemical characterization of NPs included size, morphology, zeta potential, release profiles and encapsulation efficiencies, analyzed using scanning electron microscopy, a zeta-sizer and UV–vis spectrometry. The cytotoxic and inhibitory effects of NPs were determined using a methyl thiazolyl tetrazolium assay. Immunostimulatory effects of the NPs were detected by Griess reaction and ELISA tests to determine nitric oxide and cytokine levels, respectively. According to the results, DOX and antigen-loaded PCL NPs ranged between 240 nm and 290 nm. Antigen and drug-loaded NPs appear less toxic over macrophage cells in comparison with non-capsulated free agents. In addition, considerable inhibitory effects of antigen and drug-loaded NPs were observed at non-toxic concentrations, such as 25 and 50 μg ml−1, on human mammary cancer cell lines (p⩽ 0.0001). The amount of nitrite released from macrophages that were treated with antigen and DOX-encapsulated PCL NPs, in combination with alum and survivin RP, after 96 h incubation was significantly higher than the control, especially at 50 and 100 μg ml−1, and triggered macrophages to produce high quantities of IL-4 and IL-12 cytokines in contrast to the control. As a result, DOX and antigen-loaded PCL NPs in combination with survivin and alum adjuvant revealed significant immunostimulatory and inhibiting influence on macrophage and breast cancer cells, respectively. The outcomes revealed that antigen and drug-loaded PCL NPs supplemented with survivin RP and an alum adjuvant created an effective platform for the development of nanotechnology-based immunotherapeutic tools to inhibit breast cancer cells. However, these outputs should be supported by further in vivo studies.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46604296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
