Scientists have developed a new method that relies on fluid flow to manipulate and assemble multiple particles. This new technique can trap a range of submicron- to micron-sized particles, including single DNA molecules, vesicles, drops or cells.
Researchers have developed an optical sensor, based on nanostructured metamaterials, that's 1 million times more sensitive than the current best available - one capable of identifying a single lightweight molecule in a highly dilute solution.
Biomedical engineers have demonstrated a pioneering method for the rapid visualization and identification of engineered nanoparticles in tissue. The research is a cost-effective hyperspectral imaging method for nanomaterial analysis that may shed light on nanomaterials' potential health impacts.
