Measuring viscoelasticity without sample amount prerequisite

A shear rheometer requiring only 2 mg of sample was recently developed as mgRheo. No additional sample amount more than for typical chemical characterizations would be required. With this setup, various kinds of soft matter with limited yields can now be screened for their viscoelastic properties. This mgRheo is also friendly to advanced purification techniques with low yields of purer materials. It would facilitate us in studying the dynamics and rheology beyond the entangled linear polymers, which have been difficult to study due to the limited sample amount.
