Chitosan hydrogel micro-bio-devices with complex capillary patterns via reactive-diffusive self-assembly
(Elsevier, 2019-08-29)
We present chitosan hydrogel microfluidic devices with self-assembled complex
microcapillary patterns, conveniently formed by a diffusion-reaction process.
These patterns in chitosan hydrogels are formed by a single-step ...
Nonspecific interactions in biomedical applications
(Elsevier, 2019-12-20)
Nonspecific interactions play a major role in the microscale functioning of biological units. Exploiting these interactions in design and application of biomedical systems has been beneficial in different branches of ...
Short-sequence superadhesive peptides with topologically en-hanced cation-π interactions
(American Chemical Society, 2021-06-03)
In this study, using the surface force apparatus, we report engineered peptides with short sequences of phenylalanine (F) and lysine (K) amino acids capable of forming the most efficient cation−π interactions reported for ...
Biomimetic bottle-brush polymer coatings for fabrication of ultra-low fouling surfaces
(Wiley, 2018-11-13)
The increasing demand for long lasting antifouling surfaces has steered the development of accessible, novel, biocompatible and environmentally-friendly materials. Inspired by lubricin (LUB), a component of mammalian ...
Superlubricity of zwitterionic bottlebrush polymers in the presence of multivalent ions
(American Chemical Society, 2020-08-13)
In this study, we report lubrication properties of physisorbed zwitterionic bottlebrush polymers in the presence of
multivalent ions using the surface force apparatus. Unlike polyelectrolyte brushes, the lubrication ...
Deep tissue penetration of bottle-brush polymers via cell capture evasion and fast diffusion
(American Chemical Society, 2022-12-14)
Drug nanocarriers (NCs) capable of crossing the vascular endothelium and deeply penetrating into dense tissues of the CNS could potentially transform the management of neurological diseases. In the present study, we ...
Plasmon-free polymeric nanowrinkled substrates for surface-enhanced raman spectroscopy of two-dimensional materials
(American Chemical Society, 2020-12-21)
We report plasmon-free polymeric nanowrinkled substrates for surface-enhanced Raman spectroscopy (SERS). Our simple, rapid, and cost-effective fabrication method involves depositing a poly(ethylene glycol)diacrylate (PEGDA) ...
Phytoglycogen nanoparticles : nature-derived superlubricants
(American Chemical Society, 2021-05-07)
Phytoglycogen nanoparticles (PhG NPs), a single-molecule highly branched polysaccharide, exhibit excellent water retention, due to the abundance of close-packed hydroxyl groups forming hydrogen bonds with water. Here we ...
Nanoparticle heterogeneity : an emerging structural parameter 2 influencing particle fate in biological media?
(Royal Society of Chemistry, 2018-11-27)
Drug nanocarriers’ surface chemistry is often presumed to be uniform. For instance, the polymer surface coverage and distribution of ligands on nanoparticles are described with averaged values obtained from quantification ...
Intermolecular interactions between Bottlebrush Polymers boost the protection of surfaces against frictional wear
(ACS Publications, 2018-05-30)
Polymers exhibiting the bottlebrush (BB) architecture have excellent lubricating properties. However, to motivate their use in real life systems, they must also protect surfaces against frictional damage. In this article, ...
