abstract = {Humic acids (HAs) provide an important bio-source for
redox-active materials. Their functional chemical groups are
responsible for several properties, such as metal ion
chelating activity, adsorption ability towards small
molecules and antibacterial activity, through reactive
oxygen species (ROS) generation. However, the poor
selectivity and instability of HAs in solution hinder their
application. A promising strategy for overcoming these
disadvantages is conjugation with an inorganic phase, which
leads to more stable hybrid nanomaterials with tuneable
functionalities. In this study, we demonstrate that hybrid
humic acid/titanium dioxide nanostructured materials that
are prepared via a versatile in situ hydrothermal strategy
display promising antibacterial activity against various
pathogens and behave as selective sequestering agents of
amoxicillin and tetracycline antibiotics from wastewater. A
physicochemical investigation in which a combination of
techniques were utilized, which included TEM, BET,
13C-CPMAS-NMR, EPR, DLS and SANS, shed light on the
structure-property-function relationships of the
nanohybrids. The proposed approach traces a technological
path for the exploitation of organic biowaste in the design
at the molecular scale of multifunctional nanomaterials,
which is useful for addressing environmental and health
problems that are related to water contamination by
antibiotics and pathogens.},
