The burgeoning field of biosensing has ushered in a new era for the accurate and sensitive detection of critical biomarkers related to oxidative stress and inflammation, conditions intricately linked to a wide spectrum of diseases. Electrochemical biosensors, a cornerstone of this technological advancement, offer real-time, precise measurement of reactive oxygen species (ROS) and other oxidative stress indicators, paving the way for earlier disease diagnosis and more effective therapeutic strategies, particularly in cardiovascular and neurodegenerative disorders [1].
The integration of advanced nanomaterials has revolutionized the sensitivity and specificity of biosensors designed to quantify inflammatory markers. Nanoparticles, quantum dots, and metal-organic frameworks (MOFs) have been instrumental in enhancing the detection capabilities for key analytes like C-reactive protein (CRP) and interleukins, proving vital for the early identification and management of inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease [2].
Aptasensors, leveraging the unique binding properties of aptamers, represent another significant stride in the monitoring of oxidative stress. Their inherent stability and high specificity make them ideal for developing biosensing systems capable of detecting intracellular ROS and extracellular oxidative stress markers with remarkable accuracy, offering promising avenues for personalized medicine in conditions associated with redox imbalance [3].
Optical biosensors, particularly those employing fluorescence resonance energy transfer (FRET), are enabling the simultaneous detection of multiple inflammatory cytokines. This high-throughput capability is crucial for unraveling complex inflammatory pathways and is accelerating the discovery of novel diagnostic markers and therapeutic targets for chronic inflammatory diseases [4].
The advent of wearable biosensors marks a paradigm shift towards continuous, non-invasive health monitoring. Wearable electrochemical biosensors, specifically designed for analyzing biomarkers in sweat, provide real-time assessment of an individual's redox status, which is paramount for athletes, patients with chronic conditions, and occupational health surveillance, through the use of flexible electrodes and microfluidic channels [5].
Impedimetric biosensors are emerging as powerful tools for the detection of specific inflammatory mediators, including tumor necrosis factor-alpha (TNF-α). By employing functionalized electrodes and sophisticated signal amplification strategies, these sensors achieve the high sensitivity and selectivity required for the early diagnosis of inflammatory diseases, with a significant potential for point-of-care applications [6].
Microfluidic platforms are transforming the analysis of oxidative stress at the cellular level. Integrated systems that facilitate controlled cell culture, reagent delivery, and electrochemical detection within a single device are indispensable for comprehending the intricate cellular processes and oxidative damage implicated in disease pathogenesis [7].
