Introduction
RNAScan—a multifaceted suite of technologies for targeted RNA detection, structural profiling, and functional annotation—is poised to redefine genomic medicine, synthetic biology, and therapeutic discovery. By converging artificial intelligence (AI), single-cell resolution, CRISPR integration, and quantum computing, RNAScan will transcend its current diagnostic role to enable real-time genomic surveillance, personalized RNA therapies, and ecosystem-scale biomonitoring. This article delineates six transformative trajectories for RNAScan, grounded in technological breakthroughs and emerging applications.
