Project title, type and project number

Microfluidic methods for quantitative antibiotic susceptibility assays with single cell resolution, MAESTRO 10 No. 2018/30/A/ST4/00036, 45/2022

Project leader

prof. Piotr Garstecki


The objective of the project is to develop an analytical platform to encapsulate bacterial cells into droplets using microfluidics, incubate them and detect growth without optical labeling. In the envisioned protocol, the sample culture of cells will be serially diluted and each dilution split and mixed with multiple concentrations of antibiotic to screen inoculum density and antibiotic concentration with digital droplet assays. The assays at high and low inoculum density will allow us to count the fraction of populated droplets that produced dense colonies of bacteria. These counts will allow us to measure the single-cell Minimum Inhibitory Concentration (scMIC) level and the inoculum effect (IE) while the low-density screens will uncover the phenotypic heteroresistance, p(scMIC). The method will offer a wealth of information for research on the response of cells and bacterial colonies to antibiotics, and hopefully will guide more effective treatments regimens.

We are looking for a highly motivated postdoctoral candidate with background in microfluidics, micro engineering, optics or similar, ideally also with experience in designing and fabricating microfluidic devices. Experience in using microfluidics for biological models (microbiology, bioengineering, biochemistry, biology) is an advantage.

The successful candidate will join a multinational and interdisciplinary team of scientist and will be responsible for designing, constructing and testing microfluidic systems for microbial testing of antibiotics in high-throughput and point-of-care (POC) formats, as well as, microfluidic systems for studying bacterial interactions at a single cell resolution.

Additionally the candidate will closely cooperate with the PhD students participating in the project, providing transfer of know-how and knowledge.
