Van der Waals and electrostatic interactions are the dominant forces acting at the nanoscale and they have been reported to directly influence a range of phenomena including surface adhesion, friction, and colloid stability but their contribution on nanoparticle diffusion dynamics is still not clear. In this study we evaluated experimentally the changes in the diffusion coefficient of nanoparticles as a result of varying the magnitude of Van der Waals and electrostatic forces. We controlled the magnitude of these forces by varying the ionic strength of a salt solution, which has been shown to be a parameter that directly controls the forces, and found by tracking single nanoparticles dispersed in solutions with different salt molarity that the diffusion of nanoparticles increases with the magnitude of the electrostatic forces and Van der Waals forces.

In phytosynthesis of gold nanoparticles AuNPs , biomolecules play a vital role in biocapping the surface of particles and generating the electrostatic repulsive forces to inhibit their growth kinetics. The quantitative estimation of interparticle interactions and modification in Ostwald ripening MOR model were also done to correlate the growth kinetic of AuNPs. The X-ray photoelectron spectroscopy XPS showed the major contribution of oxygen, carbon and nitrogen elements, corresponding to polyphenolic, carboxylic and amides, in biocapping the surface of AuNPs and directing their interparticle interactions associated with growth kinetics. The MOR model exhibited an excellent agreement of predicted growth with experimental size enlargements of AuNPs, having 4. This is a preview of subscription content, access via your institution.

The rate at which colloidal particles can form biomolecular bonds controls the kinetics of applications such as particle-based biosensing, targeted drug delivery and directed colloidal assembly. Here we study how the reactivity of the particle surface depends on its molecular composition, quantified by the inter-particle rate of aggregation in an optomagnetic cluster experiment. Particles were functionalized with DNA or with proteins for specific binding, and with polyethylene glycol as a passive surface crowder. The data show that the inter-particle binding kinetics are dominated by specific interactions, which surprisingly can be tuned by the passive crowder molecules for both the DNA and the protein system. The experimental results are interpreted using model simulations, which show that the crowder-induced decrease of the particle surface reactivity can be described as a reduced reactivity of the specific binder molecules on the particle surface. Material from this article can be used in other publications provided that the correct acknowledgement is given with the reproduced material and it is not used for commercial purposes.


In this section, some common intermolecular and surface interactions are briefly introduced, such as the VDW and EDL interactions, together.

 Спасибо. Я лишь хотел спросить, есть ли в городе клубы, где собираются молодые люди - панки. - Клубы. Для панков? - переспросил бармен, странно посмотрев на Беккера. - Да.

Все, чему его учили, свидетельствовало о чрезвычайности ситуации. Тот факт, что в лаборатории систем безопасности никого нет, а монитор был выключен, больше не имело значения. Главное теперь - сам ТРАНСТЕКСТ. Чатрукьян немедленно вывел на дисплей список файлов, загружавшихся в машину в последние сорок восемь часов, и начал его просматривать.
