Today it's Pallavi Dutta's turn to don the thesis submission hat! Pallavi has made an awesome contribution to our understanding of nanopipette ion transport, and how to utilise ion rectifying pipettes for sensing DNA and pesticides at super-low analyte concentrations.

Delighted to see this work by @DulebaDominik and @Dshekemi, discussing the challenges and complexity of silane modification in nanoconfinment out in print!
pubs.rsc.org
Organosilanes are commonly utilized to attach bioreceptors to oxide surfaces. The deposition of such silane layers is especially challenging in nanoscale or nanoconfined devices, such as in nanopip...

Thrilled to see this study in collab. with @GuiryGroupUCD, led by @EmerFarell out in print! We use rectifying nanopipettes in aprotic solvent to detect trace metals in synthetic products in minutes at comparable sensitivity to ICP but with no sample prep! https://t.co/1Wp1hvmIs3

While ion current rectification (ICR) in aprotic solvent has been fundamentally studied, its application in sensing devices lacks exploration. The development of sensors operable in these solvents is...

Very pleased to see this work, led by @DulebaDominik out in it's final version. We hope that the new model, which takes into account accumulation/depletion of H+/OH- in addition to bulk electrolyte, will be useful for the nanopore and SICM communities. https://t.co/gIyCw2F8SJ

Happy to see this nice piece led by @SONeill1998 and @adri_7792, in collaboration with @GGil_Ramirez in print. We demonstrate an effective method to modify BDD electrodes using a custom synthesized diazonium and compare the layer properties to that on GC. @ucdchemistry
