摘要： 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.
