Gold nanoparticles having a particle size of 4-15 nM are synthesized by the reduction of hydrogen tetrachloroaurate trihydrate using a suitable reducing agent such as sodium citrate in the presence of unmodified \u03b1, \u03b2 or \u03b3-cyclodextrin. Core features include: projecting a composite image comprising a plurality of modulated structured light patterns, at the object; capturing an image reflected from the surface; and recovering pattern information from the reflected image, for each of the modulated structured light patterns. The polyester film has a difference between the index of refraction in the x-axis direction and the index of refraction in the z-axis direction of about 0. The media stream is then transmitted on the network for presentation on the remotely-located display. A processor manages transaction nesting for the instruction based on the instruction type of the instruction.
