Applications of Nanomaterials in Biosensing: Current Trends and Future Prospects

Topic Information

Dear Colleagues,

Due to innovations in nanotechnology and spectroscopy, the development of biosensor technology has seen considerable advances. In recent decades, the scientific community’s focus on biomolecule imaging and detection has significantly increased; as a result, novel techniques that improve sensitivity and spatial resolution have been developed, enabling biomolecules to be more accurately characterized at the nanoscale. A range of nanomaterial based-analytical techniques are currently used, each presenting unique benefits and challenges. However, achieving nondestructive, label-free nanoscale biomolecular imaging or detection under ambient conditions and in real time remains a major challenge. Nanomaterials have attracted considerable interest in the field of biosensing due to their distinctive properties, including their high surface area, increased reactivity, and adjustable physical and chemical characteristics. These properties are particularly effective for enhancing the sensitivity, selectivity, and overall performance of biosensors. Additionally, optical nanomaterials are becoming more widely used in biosensors because of their distinctive capacity to interact with light in sensitive ways, facilitating the accurate detection of biomolecules even at low concentrations. Their high sensitivity, real-time detection, label-free sensing, and capacity to multiplex numerous biomarkers at once are particularly relevant in this field. These nanomaterials can improve biosensor performance by taking advantage of characteristics such as light scattering, fluorescence, and surface plasmon resonance. Their distinct optical characteristics make them appropriate for use in environmental monitoring, medical diagnostics, and other domains requiring accurate and effective biomolecule detection. Label-free spectroscopy techniques that utilize optical nanomaterials, such as optical spectroscopy, fluorescence, and Raman spectroscopy, are highly valued when noninvasiveness is essential, particularly when studying delicate systems in their natural state. These spectroscopic methods are popular due to their ability to detect biomolecules without the need for labels or modifications.
