Modification and characterization of spider silk
Spider silk is one of the most fascinating materials in nature and its characterization and tailoring its properties is of great interest. In this course the following will be covered:
A femtosecond solid-state laser will be used to modify spider silk by producing laser induced periodic surface structures along the silk fibers
We will employ µ-Raman spectroscopy to characterize the secondary protein structure of various spider silks in pristine and modified state.
The silks will also be imaged with scanning electron and cross polarized microscopy.Saak/Encheva

Non-linear and time-resolved vibrational spectroscopy is becoming increasingly important in physical chemistry as these techniques can provide detailed insight into the fundamental properties of molecular systems and are particularly relevant for the study of molecular interaction and interfaces. In our lab we work with laser-based techniques ranging from transient absorption to 2D-IR and sum-frequency-generation (SFG) spectroscopy.
Over the course of this project students will be introduced to femtosecond lasers and have the opportunity to participate in the design and set-up of a spectrometer.
Students will gather hands-on experience with fs lasers, beam alignment, linear and non-linear optics, multidimensional spectroscopy, etc.We hope to see you in the lab :)
