Nanoliter liquid dispensing technologies used in modern automatic laboratory processes
Automatic liquid handling is a common technique for modern high-throughput laboratories. In different types of experiments in high-throughput screening liquid biosamples frequently have to be transferred between different containers or dispensed onto surfaces. The sample volume is in nanoliter scale so dispensing techniques have to deal with surface tension forces. Consequently, there is a strong demand for nanoliter liquid dispensing technologies that could be used in different types of laboratory experiments. In this article, the current nanoliter liquid dispensing technologies for modern high-throughput laboratory processes are surveyed.
