目的对新型粉末状荧光502显现手印的方法进行进一步探索和完善,确保其高效便捷和科学准确。方法将PolyCyano UV粉末加热至230℃使其升华,待该粉末在手印纹线上聚合附着后用长波紫外线或蓝光激发拍照,并与初步研究结果相比较。结果 大部分非渗透性光滑客体表面上的汗潜手印均有很好的显现效果。结论 该方法使显现流程更加高效便捷、显现时间短、无需二次染色增强、不破坏生物检材,适合推广使用。

Fingerprints on different types of non-porous objects, including glass, metal, porcelain, plastic and enamel, were developed by using PolyCyano UV Powder (Foster+Freeman Ltd.). The results showed that fingerprints on most smooth objects can be developed effectively.
