Andrographispaniculata, Syzygiumaromaum, Zingiber officinale Rose, Houttuyniacordata, Glycyrrhizauralensis Fisch. The active ingredients in herbs are extracted by ultrasound in a water-ethanol solvent system and made in the form of a nanometer complex, then mixed in specified proportions to form the product. The product was evaluated cytotoxicity by MTT (3-(4,5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) assay and evaluated the growth inhibition effect of H5N1 virus. Result: The complex of active ingredients in the composition has the nanometer size, the main size is 443 nm, the zeta potential is -11.9 mV. The inhibitory activity of the H5N1 virus was dose-dependent, and a concentration of 3 mg/mL completely inhibited the growth of the H5N1 virus in the erythrocyte agglutination test.","PeriodicalId":16532,"journal":{"name":"Journal of Nanomedicine & Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79228366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The range of standard therapies for disorders affecting CNS is largely limited for many patients. Nonetheless, nanoparticle-based drug delivery offers itself to be a promising strategy for effective drug delivery into the brain, addressing the frequently arising complications with blood-brain barrier crossing. This study compared the drug adsorption ability and the surface chemistry of two types of silicon nanoparticles (Si-NPs). Si- NPs were prepared using two methods: electrochemical etching of Si wafers (Si-E) and low-pressure plasma synthesis (Si-P). Silicon nanoparticles were characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and nitrogen physisorption (method of Barrett, Joyner, and Halenda (BJH) and method of Brunauer, Emmett and Teller (BET)). The size and morphology were characterized by high-resolution transmission electron microscopy (HRTEM) linked with energy-dispersive X-ray spectroscopy (EDAX) and dynamic light scattering (DLS), respectively. The concentration of the drug substance that was captured by the silicon-based drug delivery system was determined by ultra high-performance liquid-chromatography-diode-array (UHPLC-DAD) method. Results of XPS showed that the Si-E are more oxidized than Si-P. The BET analysis showed us that the Si-E have more surface area, pore volume and grain size then the Si-P, and Si-P have a bigger pore size than Si-E. We also demonstrated by XRD that silicon nanoparticles prepared by both methods have a crystalline structure. The Si-P adsorption analysis of the model compound (ferulic acid) showed better adsorption ability than Si-E. The size of the Si-P (40- 120 nm) was also measured by HRTEM.","PeriodicalId":16532,"journal":{"name":"Journal of Nanomedicine & Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91038729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article points out the possibilities of overcoming the same problem set from a device perspective by taking advantage of the merits of nanotechnologies. At the same time, open research issues and challenges are identified to spark new interests and developments in this field. Devices that use wireless communication range from RFID tags to TV receivers, and satellites to mobile phones. The availability of internet access from tablets and mobile phones is growing at an exponential rate, causing increasing demands on the performance of wireless networks and mobile devices. Some passive components necessary in wireless devices, such as inductors and capacitors, cannot be minimized as quickly as transistors and integrated circuits. This imbalance makes it likely that the performance requirements of mobile handsets will exceed the capabilities of current RF technologies within the next 10 to 15 years. As well as the global growth in mobile internet access via tablets and smartphones, wireless sensors, health monitoring systems and other devices dependent on wireless communication are becoming more and more prevalent. Developing more compact, more efficient, and less expensive wireless communication devices will have significant impact on these areas and enable new solutions for healthcare services, logistics and environmental monitoring. The devices that use wireless communication ranges from RFID tags to television set receivers and satellites to mobile phones. The availability of internet access from mobile devices is growing at an exponential rate that causes rising demand on the wireless network and mobile devices' performance. As the type of activities that consumers are engaging in over the wireless connections is changing day in day out, it has been an increased need for the devices to change also. For instance in radios, the increasing quantity of mobile internet traffic there has been increased the need for additional frequency for support. The modern world is becoming an intelligent interactive environment that has needs novel autonomous sensors with wireless communication links that require to be incorporated into an everyday object. This is the reason why sensors that are nanoenabled integrated with small RF transceivers are useful in monitoring air quality, water pollution among other aspects. The main drivers of changing into nanotechnology in wireless devices are needed for high performance, reduced consumption of power as well as reduced compact size.","PeriodicalId":16532,"journal":{"name":"Journal of Nanomedicine & Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86200179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
