The understanding of surfaces and how they interact with their environment can advance understanding and functionality of many systems. Understanding surface properites is especially important in nanofabrications and chemical and biological sensors. For example by tailoring surface properties cells can be directed or patterned on a surface (example shown below).
Raman spectroscopy and electrochemistry can also be used.
