Surface plasmon-mediated chemical reactions (SPMCRs) have emerged as a rapidly developing research area within plasmonics, where localized surface plasmons enhance light-matter interactions at the nanoscale, facilitating the efficient conversion and utilization of photon energy to drive chemical processes. SPMCRs have shown great promise for driving chemical processes under significantly milder reaction conditions that are often inaccessible using conventional thermochemistry. Over the past few decades, various reactions have been extensively studied using advanced experimental and theoretical tools. However, discerning the individual contributions within SPMCRs remains challenging. The efficient utilization of SPMCRs for practical applications continues to be a daunting task. This review summarizes recent advances in SPMCRs and proposes several strategies aimed at achieving a more comprehensive understanding of the chemical reaction systems.

Recent studies support that magnetic chiral nanozymes, integrating the features of chirality, magnetism, and enzyme-like catalysis, provide new insights into the synthetic methodologies and applications of chiral nanozymes. In this study, we present the design of novel magnetic chiral cobalt superstructures (CoSSs) synthesized by the regulation of complex formation kinetics of Co³⁺ with chiral ligands (L- or D-tartaric acid) under varying metal-to-ligand molar ratios and solvent polarity. This approach yielded a series of CoSSs with varying symmetry from high to low. The chiral CoSSs exhibited chirality-dependent peroxidase (POD)-like activity, demonstrating a high affinity of L-CoSSs towards substrates, with a chiral selective factor of approximately 1.37. In addition, the magneto-optical effects of the chiral CoSSs significantly enhanced their chiroptical performance from ultraviolet–visible (UV–vis) to near-infrared region. Under a magnetic field, the affinity of chiral CoSSs for substrates increases, while the chiral selective factor was modified to 0.76. This research on magnetic chiral CoSSs nanozymes opens promising new avenues for the application of artificial enzymes in fields, such as antibacterial technology, drug delivery, and biocatalysis.
