What Are the Challenges in Implementing Nanoscale Barcoding?
Despite their potential, nanoscale barcodes face several challenges. One major issue is biocompatibility; the nanoparticles used must be non-toxic and safe for use in living organisms. Additionally, the synthesis of these barcodes needs to be highly controlled to ensure uniformity and reproducibility. Lastly, the readout systems for these barcodes must be highly sensitive and accurate to detect the unique patterns without error.
