Super-multiplexed imaging and coding in the range of radio frequency

The era of the Internet has led to an information explosion, creating significant challenges for current techniques in information storage and access. High-performance strategies that expand existing methods offer a promising solution. Imaging-based approaches are vital for information perception but remain underexplored for information processing due to limited multiplexity. Here, we introduce 19F magnetic resonance imaging-Empowered information Assess and Storage Technique (FEAST), enabled by 22 fluorinated quaternary ammonium derivatives with distinct 19F chemical shifts. We developed three coding platforms for FEAST: fluorinated choline analog solutions, fluorinated deep eutectic solvents, and fluorinated ionogels. These platforms allow 2-spatial-dimensional applications, such as 16-bit encoding, “dual-color” watermarking, multiplexed Colorcodes, and encrypted QR codes, as well as 3-spatial-dimensional applications like “cubic” information storage, implanted anti-counterfeit labels, and FEAST-guided encryption. This work highlights FEAST’s potential for advanced information storage and access, which is inspiring for further developments with versatile and robust coding platforms.
