Alternatively, polymer can be infiltrated into 1D, 2D, 3D preform creating high content polymer nanocomposites. [2] Polymer nanoscience is the study and application of nanoscience to polymer-nanoparticle matrices, where nanoparticles are those with at least one dimension of less than 100 nm.
A range of polymeric nanocomposites are used for biomedical applications such as tissue engineering, drug delivery, cellular therapies. [29] [30] Due to unique interactions between polymer and nanoparticles, a range of property combinations can be engineered to mimic native tissue structure and properties. A range of natural and synthetic ...
Nanocomposite hydrogels incorporated with polymeric nanoparticles are tailored for drug delivery and tissue engineering. The addition of polymeric nanoparticles gives these hydrogels a reinforced polymeric network that is more stiff and has the ability to enclose hydrophilic and hydrophobic drugs along with genes and proteins.
For some applications, nanoparticles may be characterized in complex matrices such as water, soil, food, polymers, inks, complex mixtures of organic liquids such as in cosmetics, or blood. [133] [134] There are several overall categories of methods used to characterize nanoparticles.
Nanoparticles have been used in drug delivery for applications such as diagnosis and treatment of diseases, with polymeric nanoparticles gaining significant traction as a carrier of drugs or biomolecules over the last few decades. [5] [6] [7] These structures are extremely small, having a diameter < 100 nm. [6]
The application potential of nanoparticles in catalysis ranges from fuel cell to catalytic converters and photocatalytic devices. Catalysis is also important for the production of chemicals. For example, nanoparticles with a distinct chemical surrounding , or specific optical properties. [citation needed]
A nanogel is a polymer-based, crosslinked hydrogel particle on the sub-micron scale. [1] [2] [3] These complex networks of polymers present a unique opportunity in the field of drug delivery at the intersection of nanoparticles and hydrogel synthesis.
Example of a cellulose nanofiber network. Nanofibers are fibers with diameters in the nanometer range (typically, between 1 nm and 1 μm). Nanofibers can be generated from different polymers and hence have different physical properties and application potentials.
