Optical Tweezers and Single-Molecule Force Spectroscopy
Optical tweezers use focused laser light to trap and manipulate microscopic particles, enabling measurement of piconewton-scale forces and nanometer-scale displacements in single molecules.
BiophysicsProdrug Design and Strategies
Prodrugs are pharmacologically inactive derivatives that undergo enzymatic or chemical conversion in vivo to release the active drug, improving solubility, permeability, or targeting.
Chemical biologyFörster Resonance Energy Transfer (FRET)
FRET is a distance-dependent energy transfer mechanism between fluorophores that reports molecular proximity and conformational changes with nanometer sensitivity in real time.
BiophysicsMedicinal Chemistry: SAR and Lead Optimization
Structure-activity relationship analysis guides lead optimization by systematically modifying functional groups to improve potency, selectivity, pharmacokinetics, and safety profiles.
Chemical biologyFragment-Based Drug Design
Fragment-based drug design uses low-molecular-weight fragments to identify efficient binding motifs, which are then elaborated into potent lead compounds through structure-guided optimization.
Chemical biologyLigand Binding Kinetics and Equilibrium
Ligand binding kinetics describes the rates of association and dissociation between a ligand and its target, while equilibrium binding reflects the affinity under steady-state conditions.
BiophysicsHigh-Throughput Screening and Assay Development
High-throughput screening uses automated instrumentation and large compound libraries to identify active molecules against biological targets, with robust assay design being critical for success.
Chemical biologyChemical Genetics and Chemogenomics
Chemical genetics uses small-molecule probes to study protein function in living systems, while chemogenomics systematically links compounds to their genomic targets.
Chemical biologyProtein Folding and Thermodynamics
Protein folding is the process by which a polypeptide chain adopts its native three-dimensional structure, driven by hydrophobic forces, hydrogen bonding, and van der Waals interactions.
