Summary


Dr Alex Ivanov is an IC Research Fellow and a group leader at Imperial College London. His research focuses on the innovation of novel nanoscale sensors and platforms for single-molecule 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 applications Nano Lett (2011), development of methods for high precision fabrication and positioning of nanoelectrodes in a nanopore ACS Nano (2014), optical/plasmonic nanopore platforms Nano Lett (2013, 2015); ACS Nano (2015A),methods for on-demand delivery of single DNA molecules  ACS Nano (2015B), single molecule detection from ultra-dilute samples using molecular traps Nature Comm (2016), nanopore/field effect transistor devices for selective sensing Nature Comm (2017A), zeptolitre confinement of single molecules Nano Lett (2017) and selective single molecule protein detection in human serum, Nature Comm (2017B), to name a few.
