IISER-Brahmapur's Nanotech Biosensor Detects Turner Syndrome DNA Sequences
Scientists at a research institute in India have made a special sensor that can find a rare health condition called Turner Syndrome.
Turner Syndrome happens when a girl is born missing part of one of her X chromosomes.
The sensor uses tiny gold star shapes and special molecules to spot the DNA signs of this condition very quickly.
It works like a super-sensitive detective that can find a tiny clue in a big sample.
Usually, doctors need big machines and lots of time to find this condition.
This new sensor is faster, cheaper, and easier to use.
Turner Syndrome affects about one in every 2,500 girls born.
Girls with it may be shorter, have delayed puberty, and sometimes have heart or kidney problems.
Finding it early helps doctors take better care of these girls.
The sensor might also be changed to find other inherited diseases in the future.
Researchers at IISER-Brahmapur developed a nanotechnology-enabled biosensing platform that detects DNA sequences associated with Turner Syndrome.
The platform combines a nucleotide-guided covalent organic framework (COF) integrated with gold nanostars for rapid, sensitive detection.
Turner Syndrome, caused by complete or partial loss of one X chromosome in females, affects nearly one in 2,500 female births.
The biosensor offers a promising alternative to conventional chromosomal karyotyping, which is labour-intensive, time-consuming, and requires specialised laboratory facilities.
Published in Advanced Functional Materials, the technology still requires clinical validation but could be adapted for other inherited genetic disorders.
