The
characterization and analysis of biosensors are essential for understanding
their performance and optimizing their design for various applications. This
chapter provides information on the calibration and standardization protocols, evaluation
of performance parameters, data analysis techniques, and analytical tools and
techniques utilized in biosensor characterization. Calibration and
standardization protocols ensure accuracy and reproducibility, while the
evaluation of performance parameters such as sensitivity, selectivity, and
dynamic range is critical for assessing biosensor effectiveness. Data analysis
techniques, including chemometrics and machine learning algorithms, aid in
interpreting complex biosensor data. To effectively characterize biosensors, a
diverse array of analytical tools and techniques are employed. Surface
functionalization methods are crucial for enhancing the specificity and
performance of biosensors, allowing for the immobilization of biomolecular
recognition elements onto the nanomaterial surface. Spectroscopic and
spectrometric techniques provide valuable insights into the physicochemical
properties of nanomaterials and their interactions with biomolecules.
Electrochemical characterization methods play a role in evaluating the
electrochemical behavior and performance of biosensors. Microscopic techniques
such as electron microscopy and atomic force microscopy (AFM) offer
high-resolution imaging of biosensor surfaces, facilitating the visualization
of nanomaterial morphology and surface modifications. Future technologies are
expected to advance by the availability of higher resolution detectors to
provide more sensitive and accurate characterization of nanomaterials to be
employed in biosensors.
