Let's wait to be afraid of nanoparticles

Nanotoxicology is developing intensively. Maybe it will take another five years until there are statistics on the impact of nanoparticles on health. In any case, it is impossible to be afraid in advance of what may not be dangerous.

RNA origami

Nanoparticles from RNA can be used in various fields of engineering and medicine, if you cope with the chemical instability of RNA and its rapid destruction by enzymes-RNases. This was achieved simultaneously by two groups of researchers.

Macroporous ferrogel squeezes medicines into a sore spot

The new material, called macroporous ferrogel, can be compressed up to 70 percent by a magnetic field. Reversible metered compression removes drugs or cells and proteins embedded in the gel from the gel.

Nanofilters: pure water without deception

The filter is based on ordinary cotton fabric, which is immersed for a few minutes in a solution of silver nanowires (precious metal takes very little to produce them, scientists say) and carbon nanotubes.
