Nanomaterial-Enabled Electrochemical and Optical Biosensors for Rapid Biomarker Detection
This research community develops high-sensitivity diagnostic tools that use engineered nanomaterials to detect specific biological markers, primarily for rapid disease screening and point-of-care testing.
The work centers on integrating gold and silver nanoparticles, quantum dots, and graphene derivatives into electrochemical, photoelectrochemical, and colorimetric sensing platforms. Recurring methods include lateral flow assays, electrochemiluminescence, and signal amplification strategies designed to lower detection limits for targets such as cancer biomarkers, nucleic acids, and pathogens. The community frequently employs molecularly imprinted polymers and aptamers to achieve selective recognition of analytes in complex biological samples, prioritizing rapid, label-free, and simultaneous detection capabilities.
The largest share of the community's output is found in gold research, representing 4.4% of all gold-related papers tracked, and 8,162 papers in total. Ruthenium research also holds a significant share at 1.3%, followed by silver at 1.2%.
The community comprises 29,708 papers, publishing most frequently in Biosensors and Bioelectronics, Analytical Chemistry, and Sensors and Actuators B Chemical.
Recent work focuses on integrating artificial intelligence with biosensor platforms, developing wearable aptamer-based sensors for continuous monitoring, and applying these technologies to food safety and antibiotic resistance diagnostics.
