“…[16] For single layer graphene, the {2110} spots appear less intense relative to the {1100} spots. [41] In the present case, they are of equal intensity. As both the TEM and SAED patterns are very sharp, the carbon nano-sheet synthesized in the present work is expected to have a perfect crystalline structure and a regular hexagonal carbon framework.…”

Graphene‐like carbon nano‐sheets are prepared from dextrin, with cetyltrimethyl ammonium bromide (CTAB) as stabiliser, by the action of concentrated sulfuric acid. Oxidation of such sheets produce graphene oxide (GO) like material. These are characterized in the usual manner and their photophysical properties are explored. Binding of certain drug molecules with carbon nano‐sheet is investigated fluorimetrically. Finally, action of carbon nano‐sheets on normal and cancer cell lines revealed that the sheets have no effect on normal cells, but induce apoptosis on cancer cells. Also, these carbon nano‐sheets behave very similar to reduced graphene oxide platelets.

“…The E. coli expression system is highly efficient and costeffective expression system, and selected in this study since nesfatin-1 has no amino acid with posttranslational modification [15,16]. To avoid the shortcoming that small polypeptides are usually poorly translated and easily subjected to proteolysis in E. coli, the native "fusion partner" was introduced.…”

Nesfatin-1 is a newly discovered satiety molecule expressed mainly in the hypothalamic nuclei. It suppresses both short-term and long-term appetite. Six synthetic deoxyoligonucleotides overlapped by PCR encoding nesfatin-1 were cloned into a pET28a vector after the hexa-histidine-tagged multiple cloning sites sequence with an enterokinase recognition site incorporated in-between. The recombinant plasmid was transformed into Escherichia coli strain Rosetta to express the fusion protein, which constituted 27% of the total cell proteins. After purified by Ni-sepharose affinity chromatography, the fusion protein was treated with enterokinase to release nesfatin-1. The nesfatin-1 sample was further purified with reverse-phase high performance liquid chromatography (HPLC), and its molecular weight was determined by mass spectrometry. The biological activities of recombinant nesfatin-1 were also assessed using in vivo animal models. The method described here promises to produce about 8 mg biologically active nesfatin-1 with homogeneity over 98% from 1-L shaking flask culture of E. coli, which can be considered as an easy and cost-effective way to synthesize nesfatin-1.

“…of Ag NPs. [47,48] Before the electroless deposition, the samples are immersed in a solution of 5% hydrogen fluoride (HF) to remove a thin native oxide layer from the SiNW outer surface, which probably has built up after the CVD growth process. The SiNWs are immersed into an AgNO3/HF (0.5 mM of AgNO3, 9% HF) aqueous solution during various time intervals (20, 40, and 60 s) at room temperature.…”

Photobleaching effect is an immense problem in optical spectroscopy, especially when fluorophores are adsorbed on metal nanoparticles (NPs). Nevertheless, little effort has been assigned to the study of fluorophore photostability under this condition. In this paper, the effect of photobleaching on the Raman signal enhancement factor (RS‐EF) of dye molecules on Ag‐modified silicon nanowire (SiNW) substrates is investigated. For this purpose, SiNWs are fabricated by using the vapor–liquid–solid growth mechanism and decorated with Ag NPs by means of electroless deposition method. This process provides the possibility of forming uniformly and tightly packed Ag NPs on SiNWs. The effect of photostability of the crystal violet as analyte molecules on surface‐enhanced Raman spectroscopy is investigated as a function of time evolution and laser power. The influence of Ag NP deposition time on Raman signal enhancement is explored. Our work shows how we can optimize the excitation power for achievement of higher RS‐EF and, consequently, lower detectable concentration. Time evolution of surface‐enhanced Raman spectroscopy signal shows an exponential decay behavior, which indicates an almost uniform distribution of EFs. Capability of our nanostructure is assessed for different concentration, and subsequently, limit of detection of 10 pm with RS‐EF of 2.4×109 is obtained. Copyright © 2017 John Wiley & Sons, Ltd.
