The new core-shell nanoparticles are highly versatile and are used in printing sensor arrays that measure levels of multiple amino acids, metabolites, hormones, or drugs in sweat or bodily fluids simply by using multiple nanoparticle "inks" in a single array.

…cell-specific gene expression patterns, which ensure that a brain cell is different from a skin cell, are partly determined by the three-dimensional structure of the genetic material, which controls the accessibility of each gene. MIT chemists have now come up with a new way to determine those 3D genome structures, using generative artificial intelligence. Their technique can predict thousands of structures in just minutes, making it much speedier than existing experimental methods for analyzing the structures.
