The zeta potential of the protein corona around carboxyl particles has been measured using tunable resistive pulse sensing (TRPS). A simple and rapid assay for characterising zeta potentials within buffer, serum and plasma is presented monitoring the change, magnitude and distribution of proteins on the particle surface. First, we measure the change in zeta potential of carboxyl-functionalised ...
Abstract Protein coronae formed with nanoparticles confer several useful properties. However, the non‐specific nature of protein corona formation makes it difficult to deliver specific proteins for therapeutic applications. Herein, we report on construction a new type corona, termed binding‐mediated corona. This enables efficient and controllable delivery functional proteins, which is otherwise...
Unique patterns of biomarkers were reproducibly characterized by matrix-assisted laser desorption ionization (MALDI)-mass spectrometry and were used to distinguish Bacillus species members from one another. Discrimination at the strain level was demonstrated for Bacillus cereus spores. Lipophilic biomarkers were invariant in Bacillus globigii spores produced in three different media and in B. g...
Protein adsorption on nanoparticles has been a focus of the field of nanocarrier research in the past few years and more and more papers are dealing with increasingly detailed lists of proteins adsorbed to a plethora of nanocarriers. While there is an urgent need to understand the influence of this protein corona on nanocarriers' interactions with cells the strong impact of the protein source o...
Objective(s): Study and development of antifouling nanosystem for conjugation of drugs were attracting great attention in recent years. The present study aimed to develop novel curcumin-loaded silica nanoparticles containing zwitterionic coating as an antifouling system to provide protein corona free nanoformulations for curcumin. Materials and Methods: Silica nanoparticles were prepared ...
The role of nanoparticle surface hydrophobicity on its hemolytic property is established in the absence and the presence of plasma proteins. Significantly, the formation of plasma protein corona on NP surface protects red blood cells from both hydrophilic and hydrophobic NP-mediated hemolysis.
A protein corona is formed at the surface of nanoparticles in the presence of biological fluids, masking the surface properties of the particle and complicating the relationship between chemical functionality and biological effects. We present here a series of zwitterionic NPs of variable hydrophobicity that do not adsorb proteins at moderate levels of serum protein and do not form hard coronas...
