Biosensors, special Issue

"Biosensors for the Detection of Nitrogen-Based Compounds". Guest Editor: Prof Dr Maria Gabriela Almeida.

Nitrogen is present in the environment as a wide variety of chemical compounds, including nitrate, nitrite, nitric oxide, nitrous oxide, dinitrogen, ammonium, hydroxylamine, and organic nitrogen. The interconversion of these compounds in the environment constitutes the global biogeochemical cycle of nitrogen, which has been unbalanced by the human-driven input of N compounds in the soil, water, and atmosphere. This poses threats to human health and ecosystems on a global scale, demanding the firm control and monitoring of the most impactful N compounds, in accordance with (inter)national legislation. Moreover, the demand for the effective analysis of nitrogen oxides is also present in food quality control, biomedical research, and clinical diagnostics. However, the quantification of most N compounds is still facing several challenges.

In this Special Issue of Biosensors, we seek state-of-the-art research works focusing the development of improved biosensing tools that could take the lead in the assessment of nitrogen-based compounds. The submission of original research papers and review articles are both welcome.
