Physical background of our researchGold and silver nanoparticles exhibit interesting color effects in the visible spectral range, which is the resonant excitation of a coherent oscillation of the conduction band electrons at a certain frequency or color. This causes the color to be dependent color on the shape and size of the particle.In suspensions, for example, gold nanoparticles appear red in contrast to the usual yellow shimmer. With partial aggregation, the color changes more strongly to dark blue and purple. These phenomena have been known for a long time and the principal has been theoretically understood for over 100 years . We use these properties in a novel way to explore the dynamics of single biological molecules.



BackgroundMetal nanoparticles, especially those made of gold and silver, exhibit strong absorption in the visible, near-infrared spectral range, which is the result of plasmon excitation. Plasmons are collective coherent oscillations of the conduction band electrons (the so-called electron gas or plasma) against the positively charged ionic lattice. The natural oscillation of this mode in gold can be excited by light with a wavelength of about 530 nm, in silver at about 400 nm. The resonance wavelength depends on the sorroundings of the particle and especially on the shape. By synthesizing particles of appropriate shapes, the resonance wavelength can be tuned to a wide spectral range, even to infrared. The excitation manifests itself in an increased absorption and scattering at the corresponding wavelength, many orders higher than for particles of the same size and shape of other materials. The absorption cross-section can even be higher than the geometrical cross-section. This thousand-fold increased absorption at the plasmon wavelength leads to an intensive color of even very diluted colloidal gold and silver particle solutions. This special property has long been employed in the coloring of glass and is currently being discussed for a number of other applications such as amplification of non-linear optical effects, for example, of Raman scattering, the sensitive detection of biological molecules, and markers in experiments on single biological molecules.

Our measuring principle
.. is dark field microscopy using white light illumination. The light passes (green arrows) by the objective of the microscope, except for the scattered part which finds its way into the objective. Thus, the particles are seen in bright light in front of a dark background (hence the name dark field) in high contrast (larger than 1:1 000 000). This measuring principle requires a great amount of carefulness in its execution because any distortion that could come from dust particles has to be avoided.


Gold and silver particles pairs as distance sensorsgold and silver particles can be used to determine distances, because the plasmons in two neighboring particles couple and the color changes depend on the distance of the particles. Compared to other sensors based on F?rster energy transfers between two dye molecules FRET, the advantage is the indefinite lifetime of the particles that allows for continuous measurements. On the picture, you can see the change in color that occurs when two silver particles come close to each other. First, the single particles are blue but as soon as the second particle binds, the pair appears green. Since both the particles and the pair are well below the resolution of an optical microscope, they are seen as a single dot.
