• unique characteristics that include precise size control and ease of fuctionalisation [13][14][15]. The change in color of colloidal gold solutions provides information about processes that take place in the nano-size range, which has been used in detection studies based on the study by Mirkin et. al [16

• the poor separation efficiency and migration ability of the photo-excited charge carriers. A variety of effects have been made to enhance the photocatalytic performance of ZnIn2S4. For example, by size control on ZnIn2S4 [20], doping with transition metals [21] and incorporation of metal sulfides [22

• distributions of the final Au NP. Experimentally, a size window of 2 nm ≤ diameter ≤ 12 nm for Au NP can be realized if the monomer number especially of the P2VP block is properly adjusted [6]. Thus, size control as required in 1) above is principally given by the micellar approach. In practice, however, with
