Dr Alex Ivanov is IC Research Fellow and Lecturer (Asst. Prof.) at Imperial College London. 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), 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), single molecule nanotweezers that can extract single DNA, proteins and organelles from living cells, Nature Nanotechnology (2018) to name a few.

Research Interests:

Nanoelectronics and electrochemistry of single molecules

Single-molecule single-cell methods

Nanopore platforms, single-molecule delivery and detection (nucleic acids and proteins)

Label-free detection of proteins linked to neurodegeneration

Point-of-care diagnostics
