Abstract

The objective of this project is the fabrication of hollow piezoelectric micro electric mechanical systems (PZE-MEMS) arrays with suspended micro-channels integrated with a microfluidic network. The ultimate goal is to demonstrate the feasibility of characterizing viscoelastic fluids and cell mechanical properties using such system. We herein propose an application of SMRs as micro-rheological and biological sensors for real time analysis, using mainly the stiffness effect and not only mass-loading. A platform made of a microfluidic network and SMRs with PZE self-actuation and detection will allow multiplexing.

Rheology

Rheology (riːˈɒlədʒi; ) is the study of the flow of matter, primarily in a fluid (liquid or gas) state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. Rheology is a branch of physics, and it is the science that deals with the deformation and flow of materials, both solids and liquids. The term rheology was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, from a suggestion by a colleague, Markus Reiner.

Hemorheology

Hemorheology, also spelled haemorheology (from Greek ‘αἷμα, haima 'blood' and rheology, from Greek ῥέω rhéō, 'flow' and -λoγία, -logia 'study of'), or blood rheology, is the study of flow properties of blood and its elements of plasma and cells. Proper tissue perfusion can occur only when blood's rheological properties are within certain levels. Alterations of these properties play significant roles in disease processes. Blood viscosity is determined by plasma viscosity, hematocrit (volume fraction of red blood cell, which constitute 99.

Microfluidics

Microfluidics refers to a system that manipulates a small amount of fluids ((10−9 to 10−18 liters) using small channels with sizes ten to hundreds micrometres. It is a multidisciplinary field that involves molecular analysis, biodefence, molecular biology, and microelectronics. It has practical applications in the design of systems that process low volumes of fluids to achieve multiplexing, automation, and high-throughput screening.
