What is dendrimer nanotechnology?
Dendrimers are nano-sized, radially symmetric molecules with well-defined, homogeneous, and monodisperse structure consisting of tree-like arms or branches [1]. Dendrimers are nearly monodisperse macromolecules that contain symmetric branching units built around a small molecule or a linear polymer core [5-7].
Are dendrimer nanoparticles?
Introduction. Dendrimers are nano-sized, radially symmetric molecules with well-defined, homogeneous, and monodisperse structure consisting of tree-like arms or branches [1].
What are dendrimers used for?
Applications. Applications of dendrimers typically involve conjugating other chemical species to the dendrimer surface that can function as detecting agents (such as a dye molecule), affinity ligands, targeting components, radioligands, imaging agents, or pharmaceutically active compounds.
What category of nanoparticle is a dendrimer?
Dendrimer-encapsulated nanoparticles (DENs) are nanoparticles ranging from 1.5 to 10 nm that are synthesized by a template approach using dendrimers. Monometallic, bimetallic and semiconductor nanoparticles have been synthesized using this method.
How does a dendrimer work?
Dendrimers for drug delivery are employed using two approaches: (i) formulation and (ii) nanoconstruct. In the formulation approach, drugs are physically entrapped in a dendrimer using non-covalent interactions, whereas drugs are covalently coupled on dendrimers in the nanoconstruct approach.
What are metal based nanomaterials?
Metal Based Nanomaterials — These are metal based materials that we commonly regarded as quantum dots, nanogold, nanosilver and oxides with metal bases. Titanium dioxide is one such example. [1.] Metal based Nanomaterials are a focus of the biomedical and pharmaceutical industries [5.]
What are polymeric nanoparticles used for?
Polymeric nanoparticles are able to control drug release either by diffusion through polymer matrix or by matrix degradation. They have been investigated as drug-delivery systems for the site-specific targeting of tumors and for the transport of drugs across biological barriers, particularly the blood–brain barrier.
How do you make polymeric nanoparticles?
However, there are various methods used for the preparation of polymeric nanoparticles such as desolvation, dialysis, ionic gelation, nanoprecipitation, solvent evaporation, salting out, spray drying and supercritical fluid.
Which from following is component of a dendrimer structure?
Explanation: The dendrimer has three components,i.e. central core, interior dendritic structure and the exterior surface. No stem is present in the dendrimer. 4.
Which of these are examples of metal based nanoparticles?
The first category of nanomaterial comprises the pure form of metal-based nanoparticles, which are also called metal nanoparticles (e.g., silver, copper, gold, titanium, platinum, zinc, magnesium, iron, and alginate nanoparticles).
What is metal or metal oxide nanoparticles?
Metal oxide NPs are used to reinforce the mechanical and compressive strength of concrete, generate non-utility electricity in solar cells, provide flame resistance to ceramics and windows, and increase the hydration ability of cement.
