Golden Twists: pH-tuned chirality at the nanoscale for advanced nano-sensing
Chiral gold nanoparticles (AuNPs) have emerged as versatile tools for biosensing because they can selectively interact with chiral biomolecules and convert these interactions into optical signals. Recently, we functionalized AuNPs with L- and D-cysteine, obtaining chiral AuNPs with long-term stability and pronounced op...
