Measurement of Human Red Blood Cells Density by Suspended Microchannel Resonator (SMR) (CAT#: STEM-PC-0125-CJ)
Introduction
Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to the lungs to be exhaled.
The SMR uses the principle that the resonating frequency of an oscillating cantilever (visualize a diving board in motion) is proportional to its mass. The SMR is made up of a cantilever containing a tiny fluidics channel surrounded by a vacuum. When a single cell flows through the channel inside the cantilever, the resonant frequency of the cantilever changes in proportion to the mass of the cell.
Applications
Biochemistry; Biomedical
Procedure
1. Sample preparation. 2. The sample solution flows through the microchannel in the resonant cantilever, and mechanical resonance occurs to obtain data. 3. Analyse the data.
1. The SMR is a microelectromechanical systems (MEMS) device that can weigh individual cells to a precision better than one part in 1,000. 2. Using a suspended microchannel resonator, researchers can measure the relative positions of tiny particles as they flow through a fluidic channel.
