A molecular detection method utilizing the magnetically induced aggregation of silver nanoparticle (NP)-embedded silica NPs for SERS activation is described. Here, silver embedded magnetic NPs (Ag-M-dots) composed of a magnetic core and silica shells, on whose surface silver NPs were formed, were used. Because the magnetic field induced aggregated Ag-M-dots exhibit a strong SERS signal compared to the dispersed Ag-M-dots, the system allows for the detection of adsorbed Raman label compound even at the 100 fM level. Adenine was tested as a model biocompound and its Raman spectrum could be observed at concentrations as low as 1 pM. The experimental results were supported by the theoretical calculations.

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.
