Bio/Research

Our group is interested in the development of new approaches for the efficient organic and bioorganic modification of solid surfaces as well the local electrochemical modification of adsorbates on these surfaces. Our desire to attach molecules to surfaces and manipulate them is driven by the need for reliable immobilization techniques of organic molecules on solid surfaces as routes to surface passivation and incorporation of chemical/biochemical functionality at interfaces. The immobilization of organic and bioorganic molecules on solid surfaces is a central objective in the areas of nanotechnology and microarray technologies. Development of sensors and molecular electronic devices are directly related to advances in immobilization techniques and methodologies for molecular manipulation and control of surface adsorbates.

We are interested in conducting, semi-conducting and non-conducting surfaces as substrates for the modification. The goal is to develop techniques, which will have the advantages of producing more dense and uniform films in addition to being reproducible. We are presently working on the following projects:



1) The organic modification of Au surfaces

2) The organic modification of Si surfaces

3) The local manipulation of organic adsorbates on solid surfaces
