Nano particles and nano clusters

In summary, nano particles and nano clusters are both extremely small particles, with nano clusters being a group of nano particles with specific properties. However, while nano particles can be of various dimensions, nano clusters are typically a few nanometres in size. Additionally, there is some debate on whether nano clusters can be defined as a group of atoms or if they must be larger to be considered a bulk matter. Some have also theorized the existence of nanobes, extremely small living organisms found in meteorites from Mars, which challenges traditional beliefs about the size of living organisms.

nano clusters are a group of nano particles (= nano-atoms) with certain specific properties and of a few nanometres in dimension. Check this site for more info :

I am not sure whether nano clusters can be defined as a group of nano particles..as far as I know clusters are group of atoms(it can start from 3 atoms) to 10,0000 atoms or even more large enough to be called as a bulk matter!...but nano particles can be of same dimension..is n't it? if you call nano cluster as a collection of nano partilcles that is not meaning full no??
what is your openion?

have you guys read about nanobes? pretty interesting, as in originally thought to be too small to contain DNA or RNA, but apparently living anyway, and even more intriguing that nanobes have been found inside a meteorite from mars...sort of supportive of pangenesis theory.
 

1. What are nano particles and nano clusters?

Nano particles and nano clusters are tiny particles and clusters of atoms or molecules that range in size from 1 to 100 nanometers. They have unique properties due to their small size and high surface area to volume ratio.

2. How are nano particles and nano clusters created?

Nano particles and nano clusters can be created through various methods such as bottom-up approaches like chemical synthesis or top-down approaches like mechanical milling. They can also be naturally occurring or engineered.

3. What are the applications of nano particles and nano clusters?

Nano particles and nano clusters have a wide range of applications in fields such as medicine, electronics, energy, and environmental remediation. They can be used as drug delivery systems, sensors, catalysts, and more.

4. What are the potential risks associated with nano particles and nano clusters?

Some studies have shown that certain types of nano particles and nano clusters may have toxic effects on living organisms and the environment. However, more research is needed to fully understand their potential risks and how to mitigate them.

5. How are nano particles and nano clusters being regulated?

The regulation of nano particles and nano clusters varies by country, but many governments have established guidelines and regulations for their production, use, and disposal. International organizations, such as the International Organization for Standardization, also work to establish standards for the safe handling of these materials.
