利用光致发光半导体纳米晶体用于潜在指纹检测的概念，特别是与用于背景荧光抑制的相位分辨成像相一致，被简化为用磺基琥珀酸二辛酯封端的CdS纳米晶体来实践。将纳米晶体溶解在庚烷或己烷中，并以与荧光染料染色大致相同的方式施加在已经用氰基丙烯酸酯预熏的物品上，以及在没有预熏的电工胶带的粘性侧上。由于CdS可以与树枝状聚合物形成光致发光纳米复合材料，因此也进行了树枝状聚合物标记指纹的可行性研究。
The concept of utilizing photoluminescent semiconductor nanocrystals for latent fingerprint detection, especially in concert with phase-resolved imaging for background fluorescence suppression, is reduced to practice with CdS nanocrystals that are capped with dioctyl sulfosuccinate. The nanocrystals are dissolved in heptane or hexane and are applied in much the same way as staining with fluorescent dye, on articles that have been pre-fumed with cyanoacrylate ester and also on the sticky side of electrical tape without pre-fuming. Since CdS can form a photoluminescent nanocomposite with dendrimers, a feasibility examination of dendrimer tagging of fingerprints has also been conducted.
