IPHT Researchers Investigate Usefuleness of TERS Modules as Surface Analysis Tools

Scientists at the Institute of Photonic Technology (IPHT) in Jena have been utilising JPK's NanoWizard® systems

and Tip-Assisted Optics (TERS) modules to develop high spatial resolution molecular spectroscopic methods

with the aim of advancing TERS as an accessible and sensitive tool for the analysis of surfaces and boundaries

under ambient conditions. Dr Volker Deckert, head of the Nanoscopy department at IPHT has been leading the team investigating selected applications; for example heterogeneous catalytic reactions are studied because such application-oriented experiments may be used to verify and improve the functionality of the instrument and to demonstrate its practicality for ‘real’ problems. A recent example in literature include studies reporting Nanometer-Sized Lipid and Protein Domains on a Single Cell*.

Commenting on his interactions with JPK over the years, Dr Deckert said "Since 2002, all our TERS experiments

relied on instruments based on JPK AFMs. In particular, the joint development coupling and synchronising both

the spectroscopy and scanning probe parts proved to be extremely robust and reliable. JPK's support was fast

and thorough whenever a specific adaption to a new Raman microscope or detection scheme was required."

Working with Dr Deckert has been of great help to JPK Founder and CTO, Torsten Jähnke. Speaking recently in Berlin,” Jähnke said "The development of TERS required a tip-scanning system with ready-access to the optics and the multiple electronic signal possibilities. Understanding Dr Deckert's needs have helped us build in the required versatility and flexibility in the development of our latest systems culminating in the announcement of our new NanoWizard®3 NanoOptics system.”
