Novel nanoparticle-based approach detects and treats oral plaque without drugs

ScienceDaily.com: Nanotechnology News - 17 августа, 2018 - 19:53
When the good and bad bacteria in our mouth become imbalanced, the bad bacteria form a biofilm (aka plaque), which can cause cavities, and if left untreated over time, can lead to cardiovascular and other inflammatory diseases like diabetes and bacterial pneumonia. A team of researchers has recently devised a practical nanotechnology-based method for detecting and treating the harmful bacteria that cause plaque and lead to tooth decay and other detrimental conditions.

Color effects from transparent 3D printed nanostructures

ScienceDaily.com: Nanotechnology News - 17 августа, 2018 - 16:38
Structural coloration means that the microstructure of an object causes various colors to appear. For industry, this is an attractive alternative to coloring with pigments. But so far, scientists had primarily experimented with nanostructures observed in nature, or with simple, regular designs. Computer scientists now take a different, innovative approach: their tool automatically creates 3D print templates for nanostructures for user-defined colors, and their structures do not follow any particular pattern.

Taking a closer look at unevenly charged biomolecules

ScienceDaily.com: Nanotechnology News - 16 августа, 2018 - 21:30
Clinicians most often monitor antibodies because these small proteins attach to antigens, or foreign substances, we face every day. Most biomolecules, however, have complicated charge characteristics, and the sensor response from conventional carbon nanotube systems can be erratic. A team recently revealed how these systems work and proposed changes to dramatically improve biomolecule detection.

Smallest transistor switches current with a single atom in solid electrolyte

ScienceDaily.com: Nanotechnology News - 16 августа, 2018 - 17:19
Researchers have developed a single-atom transistor, the world's smallest. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the solid state in a gel electrolyte. The single-atom transistor works at room temperature and consumes very little energy, which opens up entirely new perspectives for information technology.

Novel tissue engineering scaffolds fabricated via controlled ice crystallization

Nanowerk.com - 16 августа, 2018 - 15:36
By employing 3D scaffolds with both aligned nanofibers and aligned interconnected macrochannels, researchers have taken a nanotechnology-based tissue engineering approach to accelerate the regeneration and repair of damaged tissues at the wound site by directing cells and tissues to grow towards the target site. Their hope is that this leads to the development of affordable and functional biodegradable wound dressings for accelerated healing of chronic skin wounds by promoting regeneration of local tissues.
