where to buy nanoparticles
Nanoparticles, also known as zero-dimensional materials or “nanoscale” materials, are tiny particles with an average size of one to a few hundred nanometers (nm). They have a wide range of properties because they can be made from a number of different material systems.
NPs are often coated with molecules distinct from the material they are made of, and from the medium in which they are suspended. This coating can change the particle’s properties, such as chemical reactivity and catalytic activity.
They are important components in a large variety of applications, including medicine, semiconductors, catalysis, and energy. They can exhibit unique physical, chemical, and optical properties that depend on their size, shape, and composition.
In clinical use, NPs are used for medical imaging, drug/gene delivery, and environmental monitoring. While a number of innovations have been developed, such as iron oxide contrast agents for MRI and polymer-based drug delivery systems, there is still much work to be done.
Safety issues associated with the use of NPs for medical imaging and drug/gene delivery include their potential to be absorbed through skin or eyes, as well as their potential to disrupt cellular homeostasis. However, these risks can be overcome by incorporating non-toxic or biocompatible polymers into their structure.
Several nanoparticle synthesis techniques are available, such as wet synthesis and spark ablation. Spark ablation is a promising alternative to wet synthesis due to its lower cost, faster reaction time, and the absence of post-synthesis steps such as drying and surfactant decomposition.
