CityUHK team presents sequencing-free nanoneedle method for mapping RNA in fresh tissue
A research team led by Professor Shi Peng at City University of Hong Kong has presented Spectrum-FISH, a new technique that maps RNA in fresh tissue without sequencing or amplification.
New method avoids complex workflows
The approach uses vertically aligned nanoprobes to capture molecules through a touch-and-go molecular fishing strategy. This process eliminates the need for expensive instruments and complicated tissue preparation required by other spatial omics tools. Researchers say these simplifications make the technology more practical for pathology laboratories handling time-sensitive biopsies.
Spatial context aids medical research
Existing spatial omics technologies allow scientists to see where molecules are located within tissue structures and local microenvironments. Understanding this organization helps researchers study cancer, neurobiology, and immunology more effectively. The new method aims to bring these insights to settings with fewer computational resources.
