A fluorescent protein makes millions of bacterial cells blink in unison.
UC San Diego biologists and bioengineers continue to discover interesting uses for these winking microbes. Not just visually interesting, these altered bacteria could be used to detect environmental pollutants and organisms. A bacterial sensor capable of detecting arsenic has already been developed.
These luminescent bacteria could serve as early detection devices for potentially harmful pollutants or organisms. And unlike most detection kits, these living senors could be used for continuous monitoring rather than for isolated single measurements.
