DOI: 10.1002/elps.201800393
Abstract: Point‐of‐care systems based on microchip capillary electrophoresis require single‐use, disposable microchips prefilled with all necessary solutions so an untrained operator only needs to apply the sample and perform the analysis. While microchip fabrication can be… read more here.

DOI: 10.1111/1755-0998.13247
Abstract: To characterize microbiomes and other ecological assemblages, ecologists routinely sequence and compare loci that differ among focal taxa. Counts of these sequences convey information regarding the occurrence and relative abundances of taxa, but provide no… read more here.
