Ultrasensitive chemical analysis by Raman spectroscopy.
In the Raman effect, incident light is inelastically scattered from a sample and shifted in frequency by the energy of its characteristic molecular vibrations. Since its discovery in 1927, the effect has attracted attention from a basic research point of view as well as a powerful spectroscopic technique with many practical applications. The advent of laser light sources with monochromatic phot...
متن کاملOrdered gold nanoparticle arrays as surface-enhanced Raman spectroscopy substrates for label-free detection of nitroexplosives.
Nitroexplosives, such as 2,4,6-trinitrotoluene (TNT) which is a leading example of nitroaromatic explosives, are causing wide concern. Motivated by the urgent demand for trace analysis of explosives, novel surface-enhanced Raman spectroscopy substrates based upon highly ordered Au nanoparticles have been fabricated by a simple droplet evaporation method. It is noteworthy that an ethylhexadecyld...

exploited to manipulate the average droplet size on homogeneous substrates. [ 25,26 ] In particular, it has been demonstrated that the average droplet size can be tuned through global modulation of the concentration gradient in the solutions to produce droplet heights on the order 0.01–1 μm (and hence the term “mesoscale droplets”) and droplet volumes in the 0.5–50 femtoliter (fL) range. [ 27 ]...
متن کاملCorrigendum: Towards ultrasensitive malaria diagnosis using surface enhanced Raman spectroscopy
We report two methods of surface enhanced Raman spectroscopy (SERS) for hemozoin detection in malaria infected human blood. In the first method, silver nanoparticles were synthesized separately and then mixed with lysed blood; while in the second method, silver nanoparticles were synthesized directly inside the parasites of Plasmodium falciparum. It was observed that the first method yields a s...
