Scientists learning to create nanomaterials based on micro-algae patterns
12-06-2006 · EurekAlert!Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory.

- Microbiotic technology developed for microinjection of zebrafish embryos
09-12-2007 · EurekAlert!
University of Toronto scientists recently developed a microrobotic technology for automated microinjection of zebrafish embryos. Based on computer vision and motion control, the automated microrobotic system is capable of immobilizing a large number of zebrafish embryos into a regular pattern within seconds and injecting 15 embryos (chorion unremoved) per minute with a success rate, survival rate, and phenotypic rate all close to 100 percent. The system and performance were reported in the journal PLoS ONE.
