The tool can play a significant role in removing malignant cells from our bodies.

In a medical breakthrough that has made what was once science fiction now a science fact, researchers from the university of Michigan have developed a medical observation laser where human blood is a key component.

Much to their amazement, when the researchers shone a laser into a tiny cavity that was filled with the dye-infused blood, they discovered that they could manipulate the laser’s light to their requirements.

It can be amplified in order to exaggerate the small changes in cellular activities, or even filter it in order to reduce background noise.

Current methodologies use a combination of dyes with infrared or with visible light, however the usage of these techniques makes it hard to spot small differences.

In what can be termed as a growing expertise in biological lasers, Harvard researchers had earlier used kidney and protein tissues for a laser in 2011.

This latest breakthrough is particularly helpful due to its ability to amplify minute difference which can help surgeons do a better job at tracking cellular and bodily tissues.

Thanks to this breakthrough surgeons can now scrap out the very last bit of cancerous cells from a tumour.

Although the usage of lasers from human blood sounds ominously creepy, fact is it can save human lives.
