Dr Alex Ivanov is a Lecturer (Asst. Prof.) at the Department of Chemistry. His research focuses on the innovation of novel nanoscale sensors and platforms for single-molecule detection and delivery, that enable the studying of fundamentally important molecules in chemistry, biology, and medicine. Examples include tunnelling nanopore platform for high-resolution DNA fragment sizing and sequencing Nano Letters (2011), ACS Nano (2014), Nature Communications (2021A), optical/plasmonic nanopore platforms Nano Letters (2013, 2015); ACS Nano (2015A), methods for on-demand delivery of single molecules ACS Nano (2015B), single-molecule detection in ultra-dilute (fM) samples Nature Communications (2016), nanopore/field-effect transistors for selective bioanalyte sensing Nature Communications (2017A), zeptolitre confinement of single molecules Nano Letters (2017, 2018), multiplexed single-molecule protein detection in human serum, Nature Communications (2017B, 2019,2021B), single-molecule nanotweezers that can extract single DNA, proteins and organelles from living cells, Nature Nanotechnology (2019) to name a few.
