Surface enhanced Raman spectroscopy
Maděránková, D.; Provazník, I.; Klepárník, Karel
2009 - Czech
The signal of Raman scattering in carotene solutions, enhanced on silver colloid particles was studied. The dependence of the enhancement factor on the concentration of silver particles demonstrates the potential of the method for biological applications. Byl studován signál Ramanova rozptylu v roztocích karotenu, zesílený na koloidních částicích stříbra. Závislost faktoru zesílení na koncentraci stříbrných částic ukazuje potenciál této metody pro biologické aplikace.
