Hydrodynamic focusing and electronic cell-sizing techniques.
The technique of hydrodynamic focusing, used to improve the resolution of the Coulter counter for the sizing of bacteria, was examined. Latex particles of 0.26 mum to 6.7 mum volume were used to examine the characteristics of the system with and without hydrodynamic focusing. The system then was evaluated for sizing mixed bacterial populations as well as single populations. Possible application...

Anisotropic multifunctional particles hold great promise for drug delivery, imaging, and construction of building blocks for dynamic mesostructures such as self-assembled tissues and 3-D electrical circuits. Of particular interest, multifunctional particles with unique barcodes have been suggested as diagnosis tools for rapid screening of biomolecules. For these applications, particle design is...
متن کاملPatterning of cell-instructive hydrogels by hydrodynamic flow focusing.
Microfluidic gradient systems offer a very precise means to probe the response of cells to graded biomolecular signals in vitro, for example to model how morphogen proteins affect cell fate during developmental processes. However, existing gradient makers are designed for non-physiological plastic or glass cell culture substrates that are often limited in maintaining the phenotype and function ...

متن کاملMicroflow Cytometers with Integrated Hydrodynamic Focusing
This study demonstrates the suitability of microfluidic structures for high throughput blood cell analysis. The microfluidic chips exploit fully integrated hydrodynamic focusing based on two different concepts: Two-stage cascade focusing and spin focusing (vortex) principle. The sample--A suspension of micro particles or blood cells--is injected into a sheath fluid streaming at a substantially ...
