• during the production and quality-control stages and in clinical applications [3][4][5]. Several methods for the determination of ascorbic acid concentration have been reported, such as HPLC [6], enzymatic analysis [7] and spectrophotometry [7]. However, these methods are relatively time-consuming and/or

• arrays of the NPs, in the ideal case two-dimensionally periodic arrangements. To this end, highly reliable and reproducible self-organizing processes are sought allowing a high throughput at a tolerable price. Preparation, however, has to be accompanied by a strict quality control including the particles
