| Popis: | Based on the features of ultrasonic and microwave radiation methods, bovine serum albumin-protected gold nanoclusters have been efficiently synthesized in a novel fashion via ultrasonic-microwave heating. The experimental results show that the mean diameter of Au NCs is about 3.3 nm. In particular, Au NCs are found to reach a high quantum yield of 7.1%. The prepared Au NCs powders are utilized to develop latent fingermarks. With the self-assembly development observation system, fingermarks, even the old fingermarks emit orange-red fluorescence and show clear ridge details. Consequently, developing old fingermarks deposited on different surfaces with Au NCs is an efficient and green method. |
