Microfluidic assembly of magnetic gel particles
Poster Jul 09, 2009
Monodisperse spherical magnetic gel particles containing asymmetric infrastructure were fabricated by a new microfluidics-based technique using double-emulsion droplet as templates. Double emulsions with functional cores and hydrogel shells were generated by the flow-focusing drop makers with special wettability patterning. Particles were made with a consistently anisotropic internal structure, which leads to their uniform anisotropy to perform the highly rotational controls by applying the magnetic field.
Sample preparation is a key step in the analysis process
Parameters for evaporation and their impact on analysis have been discussed
Improvements in matching the sample to the evaporation device characteristics can help reduce variability and improve recovery
Examples for choosing a system based on sample volume, types of analytes, sample load, and initial investment considerations
