When SARS-CoV-2 began its spread around the world, scientists quickly detected that the virus' Spike protein (which gives it its peculiar shape of crowns around it) was its key to entering human cells to cause infection.

Since then, the focus for developing treatments and vaccines has been on this protein. However, a group of Chilean researchers from the Center for the Development of Nanoscience and Nanotechnology (Cedenna) found that there are other key proteins that deserve attention.

Fluorescent nanoparticles will help determine the concentration of pesticides in fruits and vegetables. This technique is complementary to chromatography, which is traditionally used to detect pesticides. In addition, it would provide benefits such as a lower cost per analysis, as well as greater agility in the delivery of results.
