Firstly, patients go to health center when they feel ill, most probably after cancer cells created in their body some long time later and/or the methods by themselves are non-specific screening methods, which often resulted in late cancer detection for effective treatment and some of these methods may be destructive to normal cells or even can cause cancer. Secondly, current cancer treatment methods are non-selection and toxic those kill both abnormal and normal cells leading to serious side effects. The use of nanotechnology to health sector, particularly its ability to detect cancer in its early stage and for complete treatment along with reducing toxicity, promises to have a deep impact on healthcare in general and on cancer in particular. This new technology has already shown the potential to detect cancer in its early stage and to increase the specificity of treatment of tumor cells while leaving healthy cells undamaged through the use of the unique properties of nanoparticles. This review discusses the use of nanoparticles such as quantum dots, magnetic nanoparticles, gold nanoparticles, polymeric micelles, liposomes, dendrimers and porous silicon nanoparticles for the early detection and treatment of cancer.","PeriodicalId":16457,"journal":{"name":"Journal of Nanomaterials & Molecular Nanotechnology","volume":"44 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2017-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73762951","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}

Recently, it was found that graphene nanolayers can be obtained by shear exfoliation of liquids. Moreover, graphene synthesizes by relatively abandon material graphite. In contrast to conventional heat transfer liquid like water, nanofluids are not transparent to solar thermal applications. It has been proven beyond doubt that kerosene, diesel and gasoline based nanofluids heat transfer coefficient enhancement would improve their efficiency of applications. In this paper water, kerosene, gasoline and diesel based nanofluids containing graphene nanolayers were prepared by shear exfoliation of fluids. Presents of graphene nanolayers were confirmed by scanning electron microscopic images. A spectrophotometer used to measure the stability of water, kerosene, gasoline and diesel nanofluids. Absorption of water-graphene nanofluid was examined to analyze the effectiveness of water based nanofluid for the solar collectors.","PeriodicalId":16457,"journal":{"name":"Journal of Nanomaterials & Molecular Nanotechnology","volume":"12 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89949066","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}

Crystal sizes of the undoped and doped ZnO nanoparticles have been determined to be ∼12 nm by XRD analysis. The crystallite size of ZnO nanoparticles have been observed to be decreased by doping process. A single, broad and unresolved EPR signal with additional two resonance peaks, Ia and Ib which are believed to be related with oxygen and zinc damage centers, and have been arised for the undoped ZnO nanoparticles. Six resolved, four resolved and a single unresolved EPR resonance signals were also recorded for the Mn, Cu and Co doped ZnO nanoparticles, respectively. UV irradiation caused some organoleptic changes for undoped and doped ZnO nanoparticles. Also, some new EPR resonance lines have also been arised for UV-irradiated ZnO nanoparticles which were accepted to be originating from the formation of oxygen and/or zinc damage centers during the UVirradiation process. From UV-Vis studies, the absorbance peaks for the synthesized ZnO nanoparticles have been appeared at ∼360 nm and the mean gap energy was calculated to be 3.20-3.32 eV.

The NA was fabricated by using electrochemical anodization process under an applied voltage of 40 V for 20 hours resulting in average pore size of 45 nm characterized by Scanning Electron Microscope (SEM). The well-recognized therapeutic compound, betulinic acid (BA) was first extracted from the bark of Melaleuca cajuputi plant and further purified by column chromatography. The purified BA was incorporated with APTES using 1-hydroxybenzotriazole hydrate (HOBt) and O-(Benzotriazol-1-yl)-N,N,N’-tetramethyluronium hexafluorophosphate (HBTU) as a peptide coupling agent. The synthesized BA-APTES was silanized on top of the fabricated NA surface. The aromatic portion of 1H and 13C of the synthesized BA-APTES compound was validated by means of Nuclear Magnetic Resonance (NMR). The FTIR spectra show emerging peaks at 2900 cm-1 and 1250 cm-1 signifying the present of aldehyde and also aliphatic amine on NA, respectively. With the aid of XPS analysis, the chemical composition of BA-APTES has evidenced that the presence of the compounds on the surface of NA membrane. Hence, the authors suggest that the modified NA surface has a potential to be applied as a new material for therapeutic agent.","PeriodicalId":16457,"journal":{"name":"Journal of Nanomaterials & Molecular Nanotechnology","volume":"30 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2017-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79891757","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}
