Fluorescent Nanomaterials in Biosensing Applications
Summary
Fluorescent nanomaterials encompass a diverse class of nanoscale particles that emit light upon excitation and have revolutionised the field of biosensing. Among these, semiconductor quantum dots, carbon quantum dots, graphene quantum dots and metal nanoclusters offer unique advantages such as size‐tunable emission wavelengths, high photostability and surface‐modifiable chemistries. By conjugating recognition elements—antibodies, aptamers or molecularly imprinted polymers—to their surfaces, these nanoparticles can transduce biochemical interactions into optical signals with exceptional sensitivity and selectivity. Applications span from real‐time monitoring of disease biomarkers and pathogens to the detection of environmental toxins and heavy metals. Advances in synthetic control have improved quantum yield and biocompatibility, while strategies such as chemometric analysis of excitation–emission matrices have enhanced multiplexed detection in complex matrices. Integration with microfluidic platforms and portable devices is driving point‐of‐care diagnostics towards rapid, low‐cost and field‐deployable solutions. Remaining challenges include minimising nonspecific binding, ensuring long‐term colloidal stability in biological fluids and scaling up reproducible manufacturing. Overall, fluorescent nanomaterials have established themselves as versatile probes that bridge fundamental photophysics and practical biosensing needs on a global scale.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
