Abstract: In this study, we report a convenient, simple, economically viable and eco-friendly method for the synthesis of gold nanoparticles (AuNPs) with carboxymethyl gum kodagogu (CMGK). Carboxymethyl gum kondagogu is a nontoxic and renewable. It is used as reducing, stabilizing and capping agent for the synthesis of AuNPs without using any chemical reducing agent. The effect of various parameters such as concentration of HAuCl4 and CMKG and reaction time for the synthesis of AuNPs was studying

disease treatment. To carry out the experiment amyloid-B 42 residue was purified, as the monomer and fibril were isolated. Single-chain antibody fragments (scFvs) were selected with a high affinity for AB42 fibrils. Affinities were measured with surface plasmon resonance. They finally used kinetic screening and analyzed using microscopy. From this, they identified four single-chain antibody fragments that specifically inhibit the fibril-dependant secondary nucleation. They also suggested from this that

Attomicroscopy As explained in the previous section, this approach is a promising way for generating isolated electron pulses last only few tens of femtosecond and hundreds of attosecond. This approach has striking advantages over the conventional compression techniques[51, 52, 97, 116], which can be summarized as follows: (I) The generated electron pulse duration is limited only by the gating laser pulse duration which could be in the order of attosecond time scale[20]. But, the nanostructure system

In top-down techniques, clusters are synthesized from larger nanoparticles or bulk metal. Etching of nanoparticles using ligands (as thiols) is one of the most top-down techniques can be used for the synthesis of metal clusters. Removing the surface atoms or break the metal nanoparticles into smaller clusters by using the etching capacity of such ligands will lead to synthesize stable quantum clusters. For example, Habib et al. has used the etching of mercaptosuccinic acid protected gold nanoparticles

In the last decade, the development of Ultrafast Electron Diffraction (UED) and Microscopy (UEM) have enabled the imaging of atomic motion in real time and space. These pivotal table-top tools opened the door for a vast range of applications in different areas of science spanning chemistry, physics, materials science, and biology. The temporal resolution in UEM mainly depends on the duration of the electron pulse, which is finite due to the initial energy dispersion and the space-charge effect.

Nanoparticles are used because of their versatility in targeted drug delivery while minimizing toxicity. Gold is used as the basis for nanoparticles because it has a relatively high stability of ligand binding along with its decreased stability with other cells. Gold nanoparticles (AuNPs) also have a high concentration of glutathione, which is an antioxidant that prevents damage to cells from things like free radicals and peroxides. We are using AuNPs to carry drugs to cells infected with the Human

Fig. (1), shows the absorbance spectra for different gamma doses of PVA/Ag nanocomposite films (b to b4). In the UV region, all the samples showed absorption band at 200 nm, which is mainly assigned as transition between the Ag nanoparticles and poly(vinyl alcohol)[17]. No absorption in the wavelength range 350–800 nm was observed for both samples (b and b1) exposed to 0 KGy and 25 KGy. This is due to the time of reaction and the gamma irradiation energy is not sufficient to reduce all the AgNO3

Introduction: With upwards of 100 000 new cancer cases diagnosed yearly in Australia, research into cancer therapy and prevention has continued to increase, with approximately $252 million in funding going into this field over the past two years in Australia alone (Cancer Australia, 2016). Current cancer therapies can involve invasive surgeries or the destruction of healthy cells (Cancer Health Centre, 2011), which is why new technologies are currently in development to provide patients with an effective

EVs as Pathogenic Mediators in NASH Cells release diverse types of membrane-bound extracellular vesicles into the extracellular milieu. These can be further classified into three main subgroups based on their cellular biogenesis: exosomes, microvesicles, and apoptotic bodies.21 Exosomes (~50-100 nm diameter) originate from the multivesicular body (MVB); MVBs are well-characterized endosomal precursors of the lysosomal degradation pathway. MVBs can also fuse with the plasma membrane. In this case
