Molecularly imprinted polymers (MIPs) have recently emerged as robust and versatile artificial receptors. MIP synthesis is carried out in liquid phase optimized on planar surfaces. Application of MIPs to nanostructured materials challenging due diffusion-limited transport monomers within the nanomaterial recesses, especially when aspect ratio >10. Here, room temperature vapor-phase reported. The vapor leverages a >1000-fold increase diffusion coefficient phase, compared relax enable...
Abstract Molecularly Imprinted Polymers (MIPs) have gained prominence as synthetic receptors, combining simplicity of synthesis with robust molecular recognition akin to antibodies and enzymes. One their main application areas is chemical sensing. However, direct integration MIPs nanostructured transducers, crucial for enhancing sensing capabilities broadening applications, remains limited. This limitation mainly arises from the need precise control over MIP features (such thickness) during...

Cancer treatment, particularly chemotherapy, requires balancing efficacy and toxicity. Although traditional monitoring methods can lead to suboptimal outcomes, emerging implantable chemical sensors complement them by providing precise, real-time drug at tumor sites, although the technology remains in its early stages. Here, we introduce an ultrathin, bioresorbable biosensor for doxorubicin vivo with high spatiotemporal resolution. The sensor amplifies drug’s fluorescence, enabling successful...
Reconfiguration of chemical sensors, intended as the capacity sensor to adapt novel operational scenarios, e.g., new target analytes, is potentially game changing and would enable rapid cost-effective reaction dynamic changes occurring at healthcare, environmental, industrial levels.
