****Macromolecular
depositoning and patterning technology developed at the USF
Surface Science Lab is now commercially available! Check here
for more info.
****We
are currently looking for Ph.D. students to
join our efforts. Projects on inorganic-organic hybrid materials
interfaces, and atomic layer deposition (ALD) related projects recently
received NSF funding. Undergraduates with research interests are
also welcome to join during semesters or summers on a flexible schedule.
Honors thesis related projects are also available. Foreign students
in search of diploma, masters, or intenship (studienarbeit/ praktikum)
research projects are also encouraged to apply.****
Welcome
to the USF Surface Science Laboratory! The
SSL focuses on the application of surface
scientific techniques on molecular and nano structured materials.
A particular focus is the investigation and fabrication of macro-molecular
interfaces. Some of the investigated topics are:
- What is the nature of the interface between
biological and inorganic materials?
- Are there chemical reactions?
- Is the bio-activity
affected by the interfaces?
- How much energy does it take to transfer
charges between inorganic and molecular materials?
The main
methods used are electrospray deposition of macro-molecular materials
thin films in vacuum directly from solution, photoemission spectroscopy,
and atomic force microscopy. The materials investigated include bio-molecules
such as DNA and proteins, as well as luminescent and semiconductive
polymers and nano-materials. The SSL also specializes in work function
measurements on a variety of materials.
Further research projects include the design
and construction of an in-vacuum macro-molecular patterning system,
fabrication of sandwich immunoassays, electrospray thin film deposition,
growth of carbon nanotubes, advanced sample preparation techniques
for matrix assisted laser desorption ionization mass spectrometry
(MALDI-MS), and ferroelectric materials' properties.
Our research is currently funded by the National
Science Foundation (NSF), and by industrial sponsors.
