Reliable data obtained through selective, sensitive, and reproducible analysis of xenobiotics and biomolecules in biological samples is fundamental to any successful drug development program. This principle also applies to many other research fields, such as forensic science, toxicology, and doping detection. The field of bioanalysis integrates complex technologies, combining sample preparation and advanced separation with mass spectrometry (MS) and nuclear magnetic resonance (NMR) detection systems, automation, and robotics. Regulatory agencies are increasingly defining the boundaries between speed and quality through method development and validation standards. Bioanalysis is an evolving discipline with many exciting opportunities in the future to further reduce sample volume, analysis costs, and environmental impact, while enhancing sensitivity, specificity, accuracy, efficiency, throughput, data quality, data processing, and handling capabilities. The journal "Bioanalysis" focuses on technologies and methods used for the detection or quantification of analytes in human or animal biological samples. Bioanalysis encourages the submission of articles describing forward-looking applications, including biosensors, microfluidics, miniaturized analytical devices, and novel hyphenated and multidimensional techniques. The journal presents essential information in a concise and clear article format, with major advancements in the field reported and analyzed by international experts, providing a credible yet accessible forum for modern bioanalysts.
