Microfluidics is the engineering or use of devices that apply fluid flow to channels smaller than 1 millimetre in at least one dimension. Microfluidic devices can reduce reagent consumption, allow well controlled mixing and particle manipulation, integrate and automate multiple assays (known as lab-on-a-chip), and facilitate imaging and tracking.
An aptamer-based nanobiosensor has been integrated into a wearable sweat sensor, allowing non-invasive tracking of the female reproductive hormone, oestradiol, with the potential to deliver sustainable solutions to female reproductive healthcare needs.
Human-based in vitro models, such as organoids and organs-on-chips, may have the potential to replace certain animal models in preclinical research. But how much ‘human’ is needed in these models?
An article in Nature Nanotechnology reports a nanopore-based single-molecule sensing method that allows control over the translocation speed of the measured molecule.
