Additionally, ultrathin, responsive layers enable the design of novel membranes for separation and purification.
The system utilised solid microneedles coated with a pH-responsive layer designed to release polyplexes when inserted into skin.
These include self-healing nanocomposite coatings, stimuli-responsive layer-by-layer nanocomposite coatings, organic-inorganic hybrid nanocomposite coatings, electroactive nanocomposite coatings based on electrically conductive polymers, and various carbon nanostructures.
Here, we describe a tumor microenvironment-responsive layer-by-layer (LbL) polymer drug carrier that actively targets tumors based on two independent mechanisms: pH-dependent cellular uptake at hypoxic tumor pH and hyaluronan-directed targeting of cell-surface CD44 receptor, a well-characterized biomarker for breast and ovarian cancer stem cells.
In order to realize a controlled drug release, a pH stimuli-responsive polyelectrolyte layer-by-layer (LbL) assembly has been used to coat the porous matrixes.
This work describes the ability to synthesize thermally responsive organic layers by initiated Chemical Vapor Deposition (iCVD).
Polymeric thin films with a stimuli-responsive surface layer have many potential applications.
Incorporating responsive organic layers into devices creates the ability to transduce chemical or biological events into optoelectronic signals.
Some novel designs such as chitosan-based glucose-responsive nanoparticles, layer by layer technique-based nanoparticles and zwitterion nanoparticles are being adopted to overcome the physiological challenges.
In the present manuscript, we have demonstrated a new two-layer nano-composite membrane consisting pH-responsive nanoporous layer and a microporous membrane supporting layer.
We have developed an optical pH sensor based on a photonic pSi film where a pH-responsive polymeric layer on top of the porous layer modulates ingress of water into the layer.
