Cover Story: Viscosity measurement of biofluids revealing the health status of individuals is of great research significance in early disease diagnosis. However, existing viscometers restricted to the large sample volumes required are not applicable to the measurement of biofluids extracted from patients. In this paper, we report a low-cost and portable microfluidic device for biosample viscosity sensing with only a small volume. Further, the reported microfluidic viscometer does not cause any alternations to the biosamples, and hence, it can combine with other measurement methods for a broad range of biomedical applications.
