Mar 25, A disposable living laser printed on chip for drug screening Nanowerk Spotlight Scientists have created a new way to monitor subtle drug interactions between bacteria and antibiotics.

By using a common office inkjet printer, researchers from NTU Singapore and China developed a disposable living laser on chip by encapsulating living bacteria inside. Strong laser emissions generated from bacteria inside the droplet will be dramatically enhanced during drug interactions. This breakthrough could enable more sensitive and high-throughput testing using micro-nano laser technology in the near future. Antibiotics have transformed the field of medicine by making it possible to treat many microbial diseases in nowadays.

Monitoring the interactions between bacteria and antibiotics pathogenic drugs is therefore a critical step for further evaluation of drug efficacies.

Different types of technologies have been developed over the past decade in search for a highly sensitive tool to monitor drug-bacteria interactions. Due to many limitations, conventional techniques usually take longer time to see an obvious result of the drug interactions.

It is therefore very challenging to identify tiny dynamic interactions. Recent advances in microlasers have demonstrated its powerful capabilities in terms of signal amplification, strong intensity, and high sensitivity for biomedical sensing. The tiny lasers serve as a highly sensitive culture-free sensor, where living bacteria were encapsulated in the micro-sized water droplets.

With the advantages of inkjet printing, the living lasers can be fabricated into a mass dimension in seconds. The cool thing is, you can then wash off the lasers and print again after detection. Then the cells along with its cell medium were injected into the office printer, where antibiotic drugs can be added directly into the pipet tips or printhead.

Hemisphere micro-droplets were then printed in array on mirror chips. Finally, the living laser array were scanned with a laser beam to generate laser emission images from whispering-gallery modes. As drug interacts with bacteria, the cell membrane would be destroyed and, in turn, more fluorescent DNA gain molecule will be released into the droplet through time and contribute to whispering gallery modes, resulting in stronger laser emission.

Because laser signal is very sensitive to the changes of the dye molecules at the droplet interface, therefore, tiny increase of the released DNA molecules can be captured and result in a significant change in the gain distribution and laser emissions. The results demonstrated that laser emission image analysis is much more sensitive than fluorescence image analysis by two orders of magnitude, where fluorescence images become saturated after a short period of time.

Most importantly, a novel concept for bioanalysis based on laser emission images was proposed to quantify the underlying biochemical and biological processes in vitro or in vivo , paving the way for high-throughput on-chip laser analysis of living organisms. Regarding the important future applications of their work, Associate Professor Shilun Feng, who is the co-author explains, "This is a fantastic work by merging microfluidic fabrication with living lasers on a chip.

The same approach could be applied to a wide range of living species, including living cells, bacteria, viruses, and proteins interactions. This technology can enable timely diagnosis and treatment with high sensitivity. With the rapid needs for drug screening against viruses, this technology could even enable viruses or bacteria to culture inside the microdroplets and monitor the dynamic interactions with drugs.
