Special Issue Information

Dear Colleague,

Biosensing technology has matured enormously owing to its simplicity and speed compared to traditional sensing methods. Diverse biosensors have been developed from various research fields based on the use of biochemical, nano- and electrochemical technology to monitor targets. When biosensors were first developed, they were used to focus on environmental toxicants and harmful materials. Due to the advantageous aspects of biosensing, the targets of biosensing have been enlarged to include chemicals, toxins, metabolites and cells. In particular, cell monitoring has been highlighted in various clinical fields for the rapid and early detection of abnormal cells and pathogens. In this Special Issue, we aim to explore the recent techniques, methodologies and applications of biosensing techniques for cell monitoring, as well as its prospective uses going forward.

We welcome authors to submit papers to this Special Issue, entitled “Biosensing Applications for Cell Monitoring.” To be considered for inclusion, articles should help to advance the field of cell monitoring based on biosensing technologies.

Disposable sensors are inexpensive, user-friendly sensing tools designed for rapid single-point measurements of a target. Disposable sensors have become more and more essential as diagnostic tools due to the growing demand for quick, easy-to-access, and reliable information related to the target. Dopamine (DA), a prevalent catecholamine neurotransmitter in the human brain, is associated with central nervous system activities and directly promotes neuronal communication. For the sensitive and selective estimation of DA, an enzyme-free amperometric sensor based on polyaniline-doped multi-walled carbon nanotubes (PANI-MWCNTs) drop-coated disposable screen-printed carbon electrodes (SPCEs) was fabricated. This PANI-MWCNTs-2/SPCE sensor boasts exceptional accuracy and sensitivity when working directly with ex vivo mouse brain homogenates. The sensor exhibited a detection limit of 0.05 μM (S/N = 3), and a wide linear range from 1.0 to 200 μM. The sensor’s high selectivity to DA amidst other endogenous interferents was recognized. Since the constructed sensor is enzyme-free yet biocompatible, it exhibited high stability in DA detection using ex vivo mouse brain homogenates extracted from both Parkinson’s disease and control mice models. This research thus presents new insights into understanding DA release dynamics at the tissue level in both of these models. Full article
