Cells

SPR can be used for drug target measurement, from drug-membrane interaction to drug-cell interaction. Distinguish between interior and penetration in real-time and unlabeled situations. The adhesion of cells on different coatings was studied.
 
There are many drivers behind cell-based studies, including tissue engineering, in vitro toxicology, drug delivery, and antimicrobial coatings. Surface plasmon resonance (SPR) was originally used to measure protein-protein interaction. It was only in recent years that researchers began to develop SPR to study living cells.
 
Some of our users use SPR to measure cell diffusion or adhesion to different biomaterials and coating surfaces.SPR can also be used as a biosensor to detect cell specific metabolites to determine cell differentiation and functionSome groups are studying biofilm formation or antimicrobial coatings
 
Five reasons for choosing SPR to examine living cells:
1. Real time measurement of living cells and bacterial adhesion
2. Able to distinguish infiltration and endocytosis without labeling
3. Nonspecific adsorption on the surface
4. Control of temperature and shear-stress
5. Combination of SPR and electrochemistry
 
Five key questions about living cells that SPR can answer:
1. What is the route of drug absorption?
2. Which kind of nanoparticles is the best carrier for drug delivery?
3. How does a nanoparticle or virus enter the cell?
4. What is the dynamics of cell attachment to the surface?
5. Which surface is the most resistant to bacterial growth?
