In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Computer simulations provide insights into plasmonic nanovesicles for drug delivery

Imagine a microscopic gold pill that could travel to a specific location in your body and deliver a drug just where it is needed. This is the promise of plasmonic nanovesicles.

New paper-based test can diagnose Zika infection within 20 minutes

MIT researchers have developed a paper-based test that can diagnose Zika infection within 20 minutes. Unlike existing tests, the new diagnostic does not cross-react with Dengue virus, a close relative of the Zika virus that can produce false positives on many Zika tests.
