Protein aggregation is phenomenon wherein protein loses its native structure and aggregates due to the adaption of non-native conformation. Amyloid aggregation formed by the accumulation of various proteins causes many diseases in humans and other organisms. Antioxidants can prevent proteins aggregation. Pulicaria undulata  extract along with phenolic compounds can increase protein stability an...

In conventional microscopes, fluorescence emission is separated from the backscattered illumination using the Stokes shift, whereby the emission occurs at a longer wavelength to the excitation. Such separation is usually achieved through a combination of wavelength filters that divide the spectrum into mutually exclusive excitation and emission bands. It is therefore impossible in these microsc...

Cationic dye Acridine orange (AO) has wide applications especially in biologicalfields such as analysis of lysosomal and mitochondria content by flow cytometryand so on. In the current work, spectroscopy of acridine orange (AO) dye at bothlow concentrations (mdye/mwater=6.25×10-5, 3.12×10-5) and high concentrations(mdye/mwater=0.002, 0.001) was studied in confined water ...

The purpose of this study is to investigate the interaction of Etofylline as an established drug for asthma remedy, with the major transport protein in human blood circulation, the human serum albumin (HSA). In this respect, the fluorescence and circular dichroism (CD) spectroscopy techniques, along with the molecular docking and molecular dynamics simulation methods were employed. Analysis of ...

The group of 2D materials contains almost all the elements of the periodic table. In contrast to the graphene sheet, they are abundant, this creates a variety of electronic properties including metals, semimetals, insulators and semiconductors. Band gaps of these materials are direct or indirect by ranging from ultraviolet to infrared, for this reason, have received much attention for nanoelect...
