FREE LIVE WEBINAR by Marit Kjaervik and Dr. Paul Dietrich

In Europe, antimicrobial resistance is responsible for approximately 25 000 deaths a year with estimated annual costs at around €1.5 billion. Drug-resistant Gram-negative bacteria are responsible for two thirds of these deaths. Innovative measurement capabilities to quantify the penetration of drugs into Gram-negative bacteria are needed to combat these deadly bacteria. This includes reliable methodologies for biofilm characterization.

The in-depth quantification of biocide concentration in biofilms can be obtained with a technique called Near-Ambient Pressure X-ray Photoelectron Spectroscopy (NAP-XPS). With NAP-XPS the biofilm dehydration is avoided during analysis, thus the structure and chemistry of the bacteria and biofilm, and its biocide uptake, is preserved.

In this webinar we will demonstrate how Near-Ambient Pressure XPS (NAP-XPS) measurements can be used to study the surface chemistry of bacteria and biofilm samples. We will also present different preparation protocols for such samples.

AGENDA

1. Introduction of EnviroESCA
2. Demonstration of automated measurement
3. Bacterial biofilms - sample preparation (liquid, dry & frozen)
4. Demonstration of NAP-XPS on a E. coli sample
5. Q&A

Visit us at our booths at the DPG 2019. We present the SPECS Group this year from April 2nd till 4th on three booths.

- Booth 64 EnviroESCA
- Booth 65 Nanonis
- Booth 70 SPECS

In addition to our new products ASTRAIOS 150 & Mimea BP5e, we also present our new website! At the SPECS booth you also have the opportunity to speak with the Service & Support about your support questions. We look forward to seeing you!
 

The Mimea Base Package BP5e is the latest evolution of the Nanonis SPM Control System. It combines exceptional signal quality, high speed and a flexible, powerful and user-friendly software interface. It’s the logical choice for the most demanding SPM applications.

With over 400 units in operation, the Nanonis SPM Control System base package 5 is the result-producing workhorse for demanding SPM experiment. The enhanced BP5e builds on the exceptional performance and signal quality of the BP5 and off ers higher speed and even  more  functionality  and  flexibility.  From signal conditioning and AD/DA conversion to fast signal processing via a comprehensive and operation-optimized graphical user interface, the Nanonis SPM Control System provides a powerful framework that can be further adapted and extended with a wide range of add-on modules. All basic processes such as scan control, spectroscopy, Z-control, fast data acquisition, data monitoring and logging, spectroscopy, atomic manipulation and lithography are included, allowing easy control of most STM and AFM operations. The software provides measurement methods and complete signal processing combined with a modern and easy to use graphical interface, off ering all necessary functionalities  and  an  efficient  workflow  for demanding SPM experiments.
