In this environment, the production of the right catalyst, complexes of copper one and the bonding of nanoparticles itself to the substrate is very efficient,

What happens when a quantum dot looks in a mirror? Abstract: The 2014 chemistry Nobel prize recognized important microscopy research that enabled greatly improved spatial resolution.
Examples of these types of light sources are fluorescent molecules, nanoparticles, and quantum dots. The JQI work uses quantum dots
namely that an"image dipole"induced in the surface of the nanowire was distorting knowledge of the quantum dot's true position.
This uncertainty in the position of the quantum dot translates directly into a distortion of the electromagnetic field measurement of the object.
The quantum dot does not have a net electrical charge but it does have a net electrical dipole, a slight displacement of positive and negative charge within the dot.

Carbon nanoparticles you can make at home Abstract: Researchers have found an easy way to produce carbon nanoparticles that are small enough to evade the body's immune system,
reflect light in the near-infrared range for easy detection, and carry payloads of pharmaceutical drugs to targeted tissues.
Unlike other methods of making carbon nanoparticles-which require expensive equipment and purification processes that can take days-the new approach generates the particles in a few hours
but that is nanoparticles with high luminescence. This is one of the simplest systems that we can think of.
The nanoparticles are coated with polymers that fine-tune their optical properties and their rate of degradation in the body.
The nanoparticles also can be made quite small, less than eight nanometers in diameter (a human hair is 80,000 to 100,
"The team tested the therapeutic potential of the nanoparticles by loading them with an anti-melanoma drug

#Environmentally friendly lignin nanoparticle'greens'silver nanobullet to battle bacteria Abstract: Silver nanoparticles have antibacterial properties,
but their use has been a cause for concern because they persist in the environment. Here, we show that lignin nanoparticles infused with silver ions
and coated with a cationic polyelectrolyte layer form a biodegradable and green alternative to silver nanoparticles.
The polyelectrolyte layer promotes the adhesion of the particles to bacterial cell membranes and, together with silver ions, can kill a broad spectrum of bacteria,
Ion depletion studies have shown that the bioactivity of these nanoparticles is limited time because of the desorption of silver ions.
when compared to an equivalent mass of metallic silver nanoparticles or silver nitrate solution. Our results demonstrate that the application of green chemistry principles may allow the synthesis of nanoparticles with biodegradable cores that have higher antimicrobial activity and smaller environmental impact than metallic silver nanoparticles.
North carolina State university researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin,
NC State engineer Orlin Velev and colleagues show that silver-ion infused lignin nanoparticles, which are coated with a charged polymer layer that helps them adhere to the target microbes,
As the nanoparticles wipe out the targeted bacteria, they become depleted of silver. The remaining particles degrade easily after disposal because of their biocompatible lignin core,
"People have been interested in using silver nanoparticles for antimicrobial purposes, but there are lingering concerns about their environmental impact due to the long-term effects of the used metal nanoparticles released in the environment,
"said Velev, INVISTA Professor of Chemical and Biomolecular engineering at NC State and the paper's corresponding author."
"The researchers used the nanoparticles to attack E coli, a bacterium that causes food poisoning; Pseudomonas aeruginosa, a common disease-causing bacterium;
The nanoparticles were effective against all the bacteria. The method allows researchers the flexibility to change the nanoparticle recipe in order to target specific microbes.
