Short Biography

Juan P. Arango is currently a Researcher in the GIBEC research group at EIA University in Colombia. Prior to his recent position, he was a visiting scholar in the department of Physiology at the University of Kentucky. He received his bachelor’s in biomedical engineering from EIA University in December 2018 and is currently finishing his master’s in biomedical engineering also from EIA University where his Project consists of developing an Optical biosensor for the detection of a model molecule. He is currently the director of the Technologies for the detection of biomolecules hotbed of research in EIA University, where he hopes to involve and train undergraduate students in the research process. He has publications in neuroscience and his current areas of interest are biomolecule detection and nanotechnology.

Biochar-derived C-Dots from Picea, Molinia caerulea and Elaeis guineensis were synthesized through a hydrothermal process, and their physicochemical and optical characteristics and environmental effects were compared. These C-Dots were characterized by techniques such as Attenuated Total Reflection–Fourier Transform Infrared (ATR-FTIR), UV-Vis spectrophotometry, fluorescence spectroscopy, dynamic light scattering (DLS), Z potential, and High-Resolution Transmission Electronical Microscopy (HR-TEM). The ecotoxicity tests were performed using the Microtox™ test, making this study one of the few that use this method. The C-Dots from Molinia caerulea showed the best quantum yield (QY) of 8.39% and moderate ecotoxicity, while Elaeis guineensis has the lowest QY (2.31%) but with zero toxicity. Furthermore, the C-Dots from Picea presents good optical properties but showed high toxicity and limits its use. Finally, all C-Dots showed functional groups that could be biofunctionalized with biomolecules, especially C-Dots from Molinia caerulea and Elaeis guineensis show potential for use in the development of optical biosensors.
