Applications of Nanoparticles
Nanoparticles have a number of practical applications, including the conversion of harmful pollutants into less harmful ones. For example, nanoparticles have the ability to transform trichloroethene, a major pollutant in industrial wastewater, into harmless carbon dioxide and water. These particles have also been shown to be effective hydrodehalogenation and reduction catalysts.
Functionalized magnetic nanoparticles
Functionalized magnetic nanoparticles (FMPs) are emerging as key players in the biomedical field, especially in biosensing. The particles can be used for several applications, including immune-magnet separation, detection of in-vivo enzyme activity, and protein separation. These nanoparticles are designed with multiple functionalities and can be fabricated by using stabilizer agents that load into the pores of the nanoparticles.
The unique properties of magnetic nanoparticles make them a promising drug delivery platform. They are also being studied for their potential as MRI contrast agents and heating mediators for cancer.
Functionalized lipid nanoparticles
A recent study shows that lipid-based nanoparticles can deliver genetic material and instructions for protein production. These nanoparticles could one day serve as therapies for genetic disorders. This research is a milestone in the field of nanomedicine. Here's what you need to know.
Using a one-step process, functionalized lipid nanoparticles are fabricated by preparing a thin lipid film. This film is then hydrated with an aqueous solvent. The mixture is then processed by vortexing or ultrasonication at temperatures higher than the phase transition temperature of lipids.
Functionalized gold nanoparticles
Functionalized gold nanoparticles (AuNPs) are gold nanoparticles with a cationic surface. These particles interact with bacterial cell membranes to disrupt their integrity, and this interaction can play a role in antibacterial and sterilising applications. Recent studies have confirmed that AuNPs with cationic surfaces are excellent antibacterial agents.
Gold nanoparticles have unique optical and chemical properties. These properties make them particularly useful in a number of bionanotechnology applications, including programmed materials synthesis, optical probes, and targeted drug delivery. Gold nanoparticles are also highly adaptable, allowing them to fit in different chemical environments and aqueous suspensions. Several of the applications of gold nanoparticles are described below.
Functionalized cellulose nanoparticles
Cellulose is a common biopolymer that is ubiquitous on Earth. It can be extracted from wood and non-woody plants. It is highly versatile and has the potential to be modified using functional moieties on the nanometer scale. Some cellulose materials have been functionalized with metals or metal oxides.
Research in this area is ongoing. Among the goals is to develop new resources for the industrial scale. One such resource is cellulose nanoparticles. These particles are biodegradable and renewable, making them promising candidates for applications in the fields of biomedicine, electronics, and catalysis.
