Abstract: Colorimetric sensors are attracting considerable interest across diverse fields owing to their ease of use, cost-effectiveness, and rapidity. Within this realm, Localized Surface Plasmon Resonance (LSPR) stands out as a favorable method for designing colorimetric sensing techniques. Sensors based on LSPR control the plasmonic characteristics of metallic Nanoparticles (NPs) to produce a noticeable alteration in color when a target analyte is detected. This article explores recent advancements in this field, including the integration of LSPR sensors with microfluidics and smartphone-based detection systems. The paper also investigates the applications of LSPR-based colorimetric sensors in diverse domains, such as environmental monitoring, biomedical diagnostics, food safety, and chemical detection. Furthermore, it sheds light on the potential limitations and prospects associated with LSPR-based colorimetric sensors, with a particular emphasis on the need for improved sensitivity, selectivity, and stability to facilitate broader practical applications.
