New "liquid biopsy" chip can detect metastatic cancer with a drop of blood
Release date: 2017-01-05
Engineers at Worcester Polytechnic Institute have developed a completely new chip that uses only one drop of blood from a cancer patient to detect metastatic cancer cells.
The amazing thing about this news is that its simple approach has brought another leap in technology.
According to the Science News Daily, this new technology is more effective than the use of microfluidics to trap cancer cells.
A member of the research team at Worcester Polytechnics explained that the device is like a small well with antibodies attached to the carbon nanotubes at the bottom of the well. The cancer cells come to the bottom of the well and are selectively attached to the antibody according to surface markers. Then they made a tiny structure called "exosome", which is how they capture cancer cells.
The "Liquid Biopsy" report is described in detail in Nanotechnology. This new technology will be the simplest laboratory experiment to help detect the early stages of cancer metastasis and enable doctors to treat them more quickly and accurately.
It is well known that cancer cells are transferred to other organs through one organ, and the process of metastasis is carried out through the blood. However, different cancer metastasis organs are also different.
For example, breast cancer is more likely to metastasize to the lungs, brain or bones. If the direction of cancer metastasis can be determined early, measures can be taken before further deterioration.
The current problem is that a small number of cancer cells float between countless red blood cells and white blood cells. However, the research team members affirmed the high precision of their technology.
