High performance surface-enhanced Raman scattering from molecular imprinting polymer capsulated silver spheres
Literature Information

Driven by the ultrasensitivity of the surface-enhanced Raman scattering (SERS) technique and the directive selection of molecular imprinting polymers (MIPs), core–shell silver-molecularly imprinted polymer (Ag@MIP) hybrid structure was synthesized to serve as a novel SERS platform. The results show that as prepared Ag@MIPs wrapped over a thin shell of MIPs are sensitive to the template molecule (Rhodamine 6G). To investigate the selectivity of Ag@MIPs, the structurally related molecules, such as Rhodamine B and crystal violet, were chosen as controls. Notably, the high sensitivity of Ag@MIPs is restrained by the non-specific recognition of Rhodamine B and crystal violet. This high SERS enhancement of the template molecule can be interpreted by the “gate effect” and/or “dummy hot spots”. We believe that the sensitivity of SERS coupled with the selectivity of MIPs could induce a promising chemosensor or biosensor for practical applications.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
