Drug discovery

Definition

Drug discovery is the complex process of identifying, developing, and bringing new pharmaceutical compounds to market. This process involves various stages, including target identification, compound screening, lead optimization, and clinical trials, all aimed at developing effective treatments for diseases. Innovative techniques in biophotonics and optical biosensors have become essential in enhancing the efficiency and accuracy of drug discovery.

5 Must Know Facts For Your Next Test

1. Drug discovery can take over a decade from initial research to market availability, involving significant financial investments and regulatory hurdles.
2. Techniques such as surface-enhanced Raman spectroscopy (SERS) provide sensitive detection methods for identifying potential drug candidates at very low concentrations.
3. Surface plasmon resonance (SPR) biosensors allow for real-time monitoring of molecular interactions, which can accelerate the lead optimization phase of drug development.
4. Förster resonance energy transfer (FRET) biosensors enable the study of molecular interactions within live cells, providing valuable insights during the drug discovery process.
5. The integration of advanced optical techniques in drug discovery not only speeds up the identification of potential drugs but also enhances their specificity and safety profiles.

Review Questions
