Carbon dots (C-dots) were used to study the binding mechanisms with serum protein, bovine serum albumin (BSA) by using two notable binding systems known as non-covalent and covalent interaction. Interaction between C-dots and BSA were estimated by Stern-Volmer equation and Double Log Regression Model (DLRM). According to the fluorescent intensity, ...

The study of binding of drug with protein is an important process in determining the activity and consequences of the drug. However, the current screening methods to investigate the drug–protein interaction are still pervaded with some disadvantages such as large requirement of sample volume and the need of expensive instrumentation. Here, we prese...

A nanocomposite was prepared from carbon nanotubes and MoSe2 (CNT-MoSe2). This nanomaterial quenches the fluorescence of fluorescein-labeled aptamers. When ciprofloxacin (CIP) binds to the aptamer, an aptamer/G-quadruplex complex will be formed and the interaction between labeled aptamer and CNT-MoSe2 nanostructures is weakened. This leads to signi...

β-Casein, a phosphoprotein representing 37% of the bovine milk caseins, has specific features promoting its application as a nanocarrier for hydrophobic bioactives. In this study, the interactions of β-casein with curcumin and vitamin D3 under the same physico-chemical conditions were investigated. The interaction kinetics have been studied by surf...

Chemistry and physics of lipids
In previous work, we have been able to determine the depth of intercalated molecules within the lipid bilayer using the solvent polarity sensitivity of three spectroscopic techniques: the 13C NMR chemical shift (δ); the fluorescence emission wavelength (λem), and the ESR β-H splitting constants (aβ-H). In the present paper, we use the quenching by ...

Typical ketone flavours (with variations in chain length, position and number of keto group, branched chain) were selected to investigate the effect of molecule structure of ketones on their interactions with myofibrillar proteins (MPs). Results showed that 2,3-pentanedione quenched the fluorescence of MPs more effectively than 2-pentanone and 3-pe...

Developing novel rare-earth complexes to rapidly and reliably sensing anions in pure water is highly challenging. Here, a series of long fluorescence lifetime polyurethane foam bonded Tb(BAA)3 chromophore porous material (Tb-PUFs) have been designed and synthesized via a simple one-step co-polycondensation reaction as an efficient fluorescent senso...

The intrinsically disordered proteins (IDPs) belong to an important class of proteins due to their higher structural flexibility and diverse functions. IDPs lack stable three-dimensional structure and exist as structural ensemble in solution. Furthermore, IDPs have been found to be associated with various neurodegenerative diseases like Alzheimer's...

Okadaic acid (OKA), a marine toxin produced by dinoflagellates, is responsible for most human diarrhetic shellfish poisoning-associated health disorders. A competitive displacement assay for OKA is described here. An OKA-binding aptamer was truncated with two sequences, one labeled with 6-carboxyfluorescein (FAM), and one with a quencher. On additi...
