Silicone Breast Implants as a Model System for Understanding Polymer Permeation in Soft Materials In Vivo

Advanced Healthcare Materials, EarlyView.
Silicone breast implants are presented as a model system for understanding polymer permeation in vivo. Rather than representing material failure, “gel bleed” emerges from solution–diffusion transport‐mediated. By integrating polymer architecture, physicochemical transport, and biointerfacial processes, this review provides a unified framework that ...

Plasma Gelation as an Overlooked Determinant of Transfection Efficiency in Protein Corona‐Coated Lipid Nanoparticles: Implications for In Vitro–In Vivo Translation

Advanced Healthcare Materials, EarlyView.
Upon contact with plasma, lipid nanoparticles (LNPs) rapidly acquire a protein corona (PC) that redefines their biological identity. In calcium‐containing environments, these coronated particles trigger the formation of a gel‐like plasma network, profoundly altering their transport properties and reducing their effective availability.

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Competition in drug binding and … the race to equilibrium

Fundamental & Clinical Pharmacology, 2022
AbstractBinding kinetics has become a popular topic in pharmacology due to its potential contribution to the selectivity and duration of drug action. Yet, the overall kinetic aspects of complex binding mechanisms are still merely described in terms of elaborate algebraic equations.

Competitive binding assays for riboflavin and riboflavin-binding protein

Analytical Biochemistry, 1982
Abstract A competitive binding procedure that can be used to determine either riboflavin or riboflavin-binding protein has been developed. Riboflavin-binding protein from chicken egg white binds tightly to DEAE-cellulose while free riboflavin does not.

Competitive hapten-antibody binding: Solution of the binding equation

Journal of Theoretical Biology, 1965
Abstract The competitive binding equation which describes the reactions between two univalent homogeneous cross-reacting haptens and antibody heterogeneous with respect to equilibrium constants has been solved. The joint probability density function of equilibrium constants can be computed directly from binding measurements; no assumption about the ...

ASSAY OF ALDOSTERONE BY COMPETITIVE PROTEIN BINDING

Acta Endocrinologica, 1970
ABSTRACT We have applied a competitive protein binding technique to the assay of aldosterone, utilizing the aldosterone binding protein (ABP) in kidney as the specific receptor molecule. Intracellular ABP was obtained from the homogenization of adrenalectomized rat kidneys in 0.25 M sucrose.

Effect of transport and competition on ligand binding

Biophysical Chemistry, 1999
We present a model to describe the physics of chemoreception in processes determined by competitive ligand binding. Our model describes the competition between various populations, such as ligands vs. blockers and receptors vs. decoys, in protein activation when diffusion is rate-determining.
