CAS Institute of Microbiology develops new microdroplet reaction screening device, coupled to cell sorting by FACS
The nanodrop system achieves nanoliter volume addition of different reagent components through high-precision micro-volume control. It is compatible with 96 and 384-well plates and can be programmed according to the pre-filled mineral oil plate. The minimum volume that can be accurately filled with a low-cost probe is 1 nL, and the volume standard deviation is less than 11% when the loading volume is 5 nL. The droplets can be by centrifugation. Multi-step reactions and concentration gradient configurations can be achieved by multiple injections of reagents. The system was used for PCR screening and single-cell phenotypic screening of pathogenic microbial single-cell resistance genes. It was also fused to a FACS system and used for single cell gene expression analysis of animal cells.

Strain-engineered bacterial consortium drives fuel cell
A group at the Institute of Microbiology of CAS has described a novel microbial fuel cell. Genetically modified cyanobacteria assimilate CO2 in visible light to form D-lactic acid, which they cannot utilize and excrete into the medium. A second microorganism,...
Silk-based composite membrane designed for salinity-gradient power plants
"Osmosis power plants" could use the potential difference between salt water and fresh water, e.g. in the estuaries of large rivers, to generate electrical energy by reverse electrodialysis. Liping WEN and colleagues from the Institute for Physics and Chemistry at CAS...
Shanghai: AI-directed „customized bus” service for commuters
In an attempt to provide better commuting services for office workers, Shanghai residents in some places can now reserve a seat in a customized bus, with a one-click reservation on their mobile phone via Alipay. The price is 18 ¥, about 1/10 the...
