Application:	Grafting nanocellulose with diethylenetriaminepentaacetic acid: Development of a novel paper additive for enhancing recycled OCC pulp fibers by functionalizing nanocellulose with DTPA (Li et al., 2022 ). Controlling multivalency and multimodality: Study on up to pentamodal dendritic platforms based on DTPA cores, illustrating DTPA′s role in multivalency and drug delivery systems (Pulido et al., 2014 ). Adsorption of Hg (II) ions by DTPA-modified cellulose: Exploration of a DTPA-modified cellulose adsorbent for removing mercury ions from aqueous solutions (Li et al., 2019 ). DTPA-functionalized multi-walled carbon nanotubes/titanium oxide-PVDF nanofiber membrane: Study on the effective separation of oil/water mixtures using a DTPA-functionalized membrane (Venkatesh et al., 2021 ).
