Abstract: The present invention pertains to liquid droplets including a polymer according to Formula (I) and to their use in an aqueous medium for the uptake of compounds from outside the droplets into the droplets for separation, storage and/or reaction of compounds inside the droplets, as well as associated methods of production of the polymer.

Abstract: The present disclosure relates to methods of making of one or more bioengineered ferritin proteins having a preselected ratio of H-subunits (ferritin heavy chain (FTH or H)) to L-subunits (ferritin light chain (FTL or L)). The disclosure further relates to cDNAs, vectors, and host cells for forming the bioengineered ferritin proteins of the present disclosure.

Abstract: A method is provided for measuring the viscosity of a fluid sample. The method comprising the steps of: (ii) providing a flow of the fluid sample; (iii) providing a component flow, wherein the component flow is a flow of the fluid sample further comprising a tracer component; (iv) generating a laminar flow of the flow (ii) with the flow (iii) in a diffusion channel, such as a microfluidic diffusion channel (2); (iv) measuring the lateral diffusion of the tracer component across the flows; and (v) determining the viscosity of the fluid from the measured diffusion profile, wherein the size of the tracer component is known or is determined.
