The co-reduction method is similar to that of the reduction method used in the synthesis of monometallic nanoparticles. The difference is that for bimetallic nanoparticle synthesis two metal precursors will be used instead of one. The two precursors along with the stabilizing agent are completely dissolved in a suitable solvent.
The cleavage/degradation of chemical bonds will enable the drugs loaded within the nanoparticle to be released into the body. Depending on the activation mechanism, Redox-Sensitive Nanoparticles can be associated with Reduction-Sensitive Nanoparticles if the chemical activation method is through reduction.
LASiS is considered a "green" method due to its lack of use for toxic chemical precursors to synthesize nanoparticles. [3] [4] [5] In the LASiS method, nanoparticles are produced by a laser beam hitting a solid target in a liquid and during the condensation of the plasma plume, the nanoparticles are formed. Since the ablation is occurring in a ...
There are several methods reported to reduce silver ion into zero-valent silver atoms: Chemical Reduction Chemical reductants can reduce silver ions into silver nanoclusters. Some examples of chemical reductants are sodium borohydride (NaBH 4) and sodium hypophosphite (NaPO 2 H 2.H 2 O). For instance, Dickson and his research team have ...
For example, traditional polymers can be reinforced by nanoparticles (such as carbon nanotubes) resulting in novel materials which can be used as lightweight replacements for metals. Such composite materials may enable a weight reduction accompanied by an increase in stability and improved functionality. [52]
A nanofluid is a fluid containing nanometer-sized particles, called nanoparticles. These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. [1] [2] The nanoparticles used in nanofluids are typically made of metals, oxides, carbides, or carbon nanotubes. Common base fluids include water, ethylene glycol, [3] and oil.
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]
The nanoparticles formed in this method have a size range between 5 and 15 nm and consist of silver hydrosol. The reduction of the silver nanoparticles is thought to come from an enzymatic process and silver nanoparticles produced are extremely stable due to interactions with proteins that are excreted by the fungi.
