Descrição geral

Polyethylene glycol (PEG) is a polyether compound that is used as an additive in cosmetics, pharmaceuticals, and food. It consists of repeated ethylene glycol units[-(CH2CH2O)n].

Aplicação

Poly(ethylene glycol) has been used as a non-absorbing polymer in aqueous dispersion or active gel assembly to stimulate the formation of filament bundles through depletion interaction.

Ações bioquímicas/fisiológicas

Polyethylene glycol (PEG) is a synthetic polymer that is used as a gold standard in bioconjugation and nanomedicine to extend blood circulation time and enhance drug efficacy. PEG-conjugated drugs are considered safe for use in humans and are approved by the U.S. Food and Drug Administration (FDA). PEG has several biomedical applications, including biosensing, imaging, and tissue engineering. It also repels protein adsorption and lowers the liver uptake, which helps in coating nanoparticles.

The formation of emulsions from multiple immiscible fluids is governed by classical concepts such as surface tension, differential chemical affinity and viscosity, and the action of surface-active agents. Much less is known about emulsification when one of the components is

The diversity of functions achieved by living cells result from the collective behavior of biological components that interact through multiple scales in time and space. The cytoskeleton constitutes one canonical system forming dynamic organizations when interacting with molecular motors. These

Living cells sense the mechanical features of their environment and adapt to it by actively remodeling their peripheral network of filamentary proteins, known as cortical cytoskeleton. By mimicking this principle, we demonstrate an effective control strategy for a microtubule-based active
