Chirality of proteinoid nanoparticles made of lysine and phenylalanine

Proteinoid nanoparticles composed of l-lysine and l-phenylalanine were prepared and showed enantioselective adsorption of l-amino acids at various pH values, emphasizing the chiral nature of the particles. The adsorption was examined using circular dichroism, isothermal titration calorimetry and ζ-potential measurements.…

Characterization of the binding of cyanidin-3-glucoside to bovine serum albumin and its stability in a beverage model system: A multispectroscopic and chemometrics study

Anthocyanins as one of the main natural groups of food colorants undergo quick color fading, which can be diminished through protein association. The stabilization of cyanidin-3-glucoside (CYG) through binding to bovine serum albumin (BSA) was investigated at pH 3.0 using…

Characterization of iron–organic matter nano-aggregate networks through a combination of SAXS/SANS and XAS analyses: impact on As binding

Nanoparticles play an important role in controlling the mobility of pollutants such as arsenic (As) in the environment. In natural waters, aggregates of nanoparticles can be constituted of organic matter (OM) associated with iron (Fe). However, little is known about…

Characterisation study of a thermal oil-based carbon black solar nanofluid

Carbon nanoparticles are very useful in solar thermal applications as they absorb much of the solar spectrum, are cheap and have excellent optical properties. Carbon nanoparticles-thermal oil-based nanofluid was prepared by a two-step method with diphenyl sulfone as the surfactant…

Characterisation of particles in solution – a perspective on light scattering and comparative technologies

We present here a perspective detailing the current state-of-the-art technologies for the characterisation of nanoparticles (NPs) in liquid suspension. We detail the technologies involved and assess their applications in the determination of NP size and concentration. (233 characters)
