Zinc chloride was used to increase the interlayer spacing of the carbon materials, and UV irradiation was used to increase the formation of charge carriers in the material. We compared the CO2 adsorption of irradiated and non-irradiated materials and observed that the UV irradiated materials exhibited greater adsorption. During adsorption testing, pressure reductions for non-irradiated samples were approximately 20–30% of the initial pressure, while irradiated samples of erandmul displayed pressure reductions of 56%. The maximum surface area was observed in samples prepared from puffed rice (982 m2/g).","PeriodicalId":13985,"journal":{"name":"International Journal of Green Nanotechnology","volume":"33 1-2 1","pages":"292-301"},"PeriodicalIF":0.0,"publicationDate":"2011-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78193723","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}

In this study, photobleaching, photostability, and mean fluorescence intensity (MFI) of FITC (fluorescein isothiocyanate)- and Dylight488- conjugated Herceptin, the humanized anti Her2 monoclonal antibody drug, were examined. After conjugation of FITC and Dylight488 to Herceptin, their degree of labeling (DOL) was calculated by a spectrophotometer. Photobleaching, photostability, and MFI of conjugates were subsequently investigated by ICC and FC on BT-474 cells.

Additionally, it has been shown that gold nanotriangles are internalized inside the cells and are compartmentalized into the cytoplasm. Thus, it has been inferred that the biologically synthesized gold nanotriangles are indeed biocompatible and, thus, are promising candidates as scaffolds for delivery of drug, genes, or growth factors inside the cells. Additionally, their unique optical properties make them a promising candidate for hyperthermic treatment of cancer.
