Biophysics
Biophysics — The application of physics principles to biological systems, including techniques for measuring peptide structure, dynamics, and interactions.
What Is Biophysics?
Biophysics applies physical methods and principles to study biological molecules. Peptide biophysics encompasses the measurement of peptide structure (CD, NMR, X-ray), binding kinetics (SPR, ITC), thermodynamic stability, and molecular dynamics.
Key Biophysical Techniques for Peptides
- CD spectroscopy: Secondary structure and thermal stability
- SPR: Real-time binding kinetics (kon, koff, Kd)
- ITC: Binding thermodynamics (ΔH, ΔS, Kd, stoichiometry)
- DLS: Hydrodynamic size and aggregation state
- Fluorescence: Conformational changes and binding
