Recent Progress in Silicon Quantum Dots Sensors: A Review

Recently, there has been a lot of interest in silicon quantum dots (Sil-QDts) because of their special opto-electronic properties. These qualities include broad absorption spectra, strong photo-bleaching stability, and size-tunable photoluminescence, which can range from visible to near-infrared depending on its size. Because of their high biocompatibility, low cytotoxicity, and vast surface modification capacity, these nanoparticles have the potential to be used in a wide range of biological and biomedical applications, including sensing, bio-imaging, and photodynamic therapy. This paper presents a thorough analysis of current developments using Sil-QDts in sensor technology. Various types of sensors that use Sil-QDts are examined in detail, such as metal ion sensors, biosensors, food quality sensors, and pesticide and pollution detectors. This paper also addresses prospective applications and future possibilities of Sil-QDt-based sensors.
