Webinar Description

Surfaces play an important role in almost all aspects of our lives. For example, biosensors that are used to detect and identify diseases are often based on chemical surface modifications. The interaction of small molecules or nanoparticles with surfaces such as lung tissue is also often dictated by surface chemistry. This means that it is critical to know as much as possible about a surface in order to both understand the interactions that occur and to be able to design surfaces that promote successful interactions. X-ray photo electron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) are two powerful surface analytical methods that have been proven to provide valuable, quantitative and qualitative information about biomaterial and biological surfaces. In this webinar we will present background, methods, and suggested guidelines for the application of XPS and ToF-SIMS to organic materials including biomaterials, cells, tissues and other organic surfaces. This is aimed at being a practical guide to help you understand the basics of these methods, know best practices for collecting and analyzing data and understand their strengths and limitations when working with organic materials.

Webinar Objectives/Topics

  • XPS Background (How does it work?)
  • XPS Instrumentation (How to collect data)
  • Sample handing (Tips on working with biomaterials, biological samples, and other organic materials)
  • XPS examples including: DNA on surfaces, polymer surfaces, and more (What can you learn from XPS)
  • ToF-SIMS Background (How does it work?)
  • ToF-SIMS Instrumentation (How to collect data along with helpful data processing tips)
  • Sample handing (Tips on working with biomaterials, biological samples, and other organic materials)
  • ToF-SIMS examples including: Monolayer films, protein orientation, lipid distributions in tissues, 2D and 3D imaging (What can you learn from ToF-SIMS along with helpful data processing tips)

Who Should Attend

This webinar is intended for researchers, students, technologists and others involved in research with biomaterial and biological surfaces who are looking to gain an understanding or broaden their knowledge on how XPS and ToF-SIMS can help in characterizing biological and biomaterial surfaces and interactions. The course will be beneficial to a large audience, from young scientists to engineers, as various aspects from instrumentation through best practices for sample handling, data collection and data analysis will be discussed in the context of characterizing organic materials with XPS and ToF-SIMS.
