Industrial pollution particles found in brains of city dwellers

Industrial pollution particles found in brains of city dwellers The team found high levels of nanoparticles made of a mineral called magnetite.More importantly, they found evidence that these nanoparticles were taken up from air polluted by industrial processes.

Microscopic magnets could revolutionize drug delivery

Microscopic magnets could revolutionize drug delivery In theory, superparamagnetic particles can be ideal for drug delivery because an external magnetic field could essentially drag them around the body.The development of larger superparamagnetic crystals could allow doctors to create special crystals for drug delivery.

Nanotubes rear their tiny heads again, this time as a stamp for electronic inks

Nanotubes rear their tiny heads again, this time as a stamp for electronic inks A team at MIT has developed a high-tech stamping process that involves a “forest” of carbon nanotubes, capable of printing electronic inks onto almost any surface, whether rigid or flexible.When densely packed, nanotubes can act as nanoscale print heads for electronic inks.

New biosensor can detect HIV earlier and faster than ever before

New biosensor can detect HIV earlier and faster than ever before This silicon chip can spot HIV in the body within days of exposure and it’s faster than all previous conclusive tests.Generally, the earliest for a definitive diagnosis of HIV infection is a month after exposure.

Chemically Custom-Tailored Graphene Could Diagnose HIV With Record Speed

Chemically Custom-Tailored Graphene Could Diagnose HIV With Record Speed And now our ability to handle individual carbon atoms could give us an advantage in the war against diseases like HIV.Currently, HIV testing takes two main forms: rapid testing via cheek swab, and the ELISA blood test that right now carries the global standard for accuracy.
