Week 11 Lab: Microfluidics

Bends in microfluidics devices Separate and sort particles

Add weight and shape in particle

Microreactors - cavities in the middle (stationery area - form assay, UV curating, heat, using time to activate the reaction)

Reynolds number

Re is the ratio of inertial forces to viscous forces. Force to viscosity

Capillary Number

Peclet Number

Types of channels

Rectangular channels Circular Channels Trapezoidal Channels V shaped channels Herringbone or grooves –> things rolling along the pattern

Cavities

Network Architectures

Chamber Filter Tesla Valve Droplet

if shapes are sandwiches - there are sealants e.g. PDMS bonding system

Stereolithography DLP

Syringe pump Flow.io Nano litres per minute

Design Challenge

Fluid3D
