Galectins, those intriguing biomarkers and therapy targets, have long challenged researchers due to their broad affinity for β-galactosides, complicating the development of selective (nano)biosensors. But fear not, a breakthrough is here! Enter a revolutionary polymer-stabilized nanoparticle biosensing platform that can ‘switch on/off’ the specificity of lacto-N-biose towards galectins using site-specific glycan fluorination. This game-changing innovation brings unprecedented selectivity to nanomaterials, potentially revolutionizing biosensing applications.
Unmasking Galectins: The Challenge and The Solution
Galectins, these soluble β-galactoside binding proteins, have raised eyebrows as therapy and diagnostics targets due to their binding promiscuity. But fear not, science rides to the rescue with a chemo-enzymatic site-specific fluorination strategy that crafts glyco-nanoparticles with adjustable selectivity towards galectins. This approach promises a new era in biosensing with tailored selectivity honed to perfection.
