Chemists use nanotechnology to fabricate novel rewritable paper

Chemists have fabricated novel rewritable paper, one that is based on the color switching property of commercial chemicals called redox dyes. The dye forms the imaging layer of the paper. Printing is achieved by using ultraviolet light to photobleach the dye, except the portions that constitute the text on the paper. The new rewritable paper can be erased and written on more than 20 times with no significant loss in contrast and resolution.

Researchers take first pictures of baby nanotubes

In a step toward understanding the factors that influence how nanotubes form, researchers have succeeded in filming them when they are only a few atoms old. These nanotube 'baby pictures' give crucial insight into how they germinate and grow, potentially opening the way for scientists to create them en masse with just the properties that they want.

How bacteria use nanodrills to kill our cells

A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial 'nanodrills' assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells' outer membranes.

Amyloid-Oligomere: Biologische Nanopartikel im Dienst der Medizin

Bisher haben Amyloid-Proteinkomplexe vor allem als mutmaßliche Alzheimer-Auslöser eher unliebsame Bekanntheit erlangt. Biochemiker und Molekularbiologen aus Ulm und Jena haben nun entdeckt, dass sich diese Komplexe aufgrund ihrer Molekülstruktur aber auch nützlich machen können.
