New portable tool for analyzing microbes in the environment, Imagine a tool that can be used to analyze germs in the ocean and other waters quickly. This reveals the health of these organisms, which are too small to be seen with the naked eye, and their response to threats to their ecosystem.

Rutgers researchers have developed such a device, a portable device that can be used to evaluate germs, look for antibiotics and analyze algae that live on coral reefs. the new portable tool for analyzing microbes in the environment.

This tool, originally developed for algal evaluation, can determine on site or in a laboratory how germs and cells react to environmental pollution such as pollution and changes in temperature or salinity of water.

This is very important for environmental biology given the impact of climate change and other stress factors on the health of microorganisms such as algae which produce harmful flowers in the ecosystem.

Our goal is to develop a new method for assessing cell health that does not depend on the use of expensive and sophisticated genomic devices. and now the portable tool for analyzing microbes in the environment.

The ability to assess and understand cell conditions without having to send samples back to the laboratory can help identify vulnerable ecosystems based on “stress indices” for their inhabitants.

This study focuses on well-studied micro-green Picochlorum algae. This tool can quickly identify whether the cell is stressed, healthy or not sensitive to environmental influences. These germs pass through micro channels which are thinner than the diameter of a human hair. Measure the impedance or the amount of electric field in the instrument that is interfering when the cell passes through a channel.

Impedance varies between population cells and reflects their size and physiological state. Both provide important health information.

Researchers have shown that electrical impedance measurements can be applied at individual and population levels.

Scientists plan to use this tool to study antibiotic resistance in various bacteria and algae that live in symbiosis with coral reefs to get a better idea of ​​coral health.
