Droplet Toolbox Opens New Possibilities for Genetic and Drug Screening of Small Animals
Genetic screens and drug screens play an essential role in the understanding of gene functions and the development of therapeutics. Genetic screens can identify genes contributing to a defect or disease state, while drug screens search for treatments that can restore normal function.

Traditionally, large-scale screens have been performed on single cells because of their small size and cost-efficiency, but with the limitation of missing the complexity of whole animals.

A team of researchers led by Hang Lu published a paper in the journal Small on a technological platform that would solve this bottleneck using droplet microfluidics.

New Screening Technique Could Accelerate and Improve mRNA Therapies
Therapeutics based on messenger RNA, or mRNA, can potentially treat a wide range of maladies, including cancer, genetic diseases, and as the world has learned in recent years, deadly viruses.  To work, these drugs must be delivered directly to target cells in nanoscale bubbles of fat called lipid nanoparticles, or LNPs — mRNA isn’t much good if doesn’t reach the right cell type.

A team of researchers at the Georgia Institute of Technology and Emory University’s School of Medicine has taken another step toward improving development of these custom-made delivery vehicles, reporting their work June 30 in Nature Nanotechnology.

Cleanroom Corner

Veeco Fiji G2 Atomic Layer Deposition System

The Veeco Fiji G2 Atomic Layer Deposition (ALD) System is a modular, high-vacuum ALD system that can accommodate a wide range of deposition modes using a flexible architecture and multiple configurations of precursors and plasma gases. The Fiji G2 is a next-generation ALD system capable of performing thermal and plasma-enhanced deposition. It has advanced features including a proprietary chamber turbo pumping system, fast process time, and improved plasma design.
Alex Weidenbach is a graduate research assistant and Ph.D. student at Georgia Tech working with W. Alan Doolittle. In the following Q&A, Weidenbach briefly discusses his work in the IEN cleanroom and gives advice to current and future users.

Job Opportunities

Postdoctoral Position
The Georgia Institute of Technology has an opening for a postdoctoral researcher to work with an interdisciplinary team to achieve fully bottom-up, high performance integrated circuits (ICs). The team’s approach combines state-of-the-art bottom-up semiconductor nanowire synthesis to create nanoelectronic devices (e.g., transistors) and ultrahigh-resolution 3-D printing to form electrical interconnects. If successful, a future IC printer promises to produce high-performance circuits (i.e., ~1 V, ~1 GHz) with a nearly limitless number of designs at low temperature in a space no larger than a desktop. The project is funded by the Defense Advanced Research Projects Agency (DARPA).
