Feature Cover: Light-Activated Nucleic Acid Amplification Systems Using Photo-Caged DNA Polymerase or Primers...

Light-Activated Nucleic Acid Amplification: Making Molecular Diagnostics "Start on Light" The cover artwork illustrates a light-triggered nucleic acid amplification platform in which dormant photo-caged DNA polymerases or primers are rapidly activated by 365 nm UV illumination. The transition from darkness to glowing activation symbolizes precise spatiotemporal control over molecular diagnostics. Flowing DNA structures and illuminated reaction pathways represent synchronized amplification with low background and high sensitivity. The highlighted polymerase and primer motifs reflect the dual photocaging strategies developed in this work, while icons representing RAA, Taq PCR, and Pfu PCR emphasize the platform's broad compatibility across amplification systems. At the base, an integrated portable fluorescence device signifies the seamless combination of UV activation and real-time detection, underscoring the potential of programmable, field-deployable molecular diagnostics and next-generation intelligent biosensing technologies.
