Souhrn

We tested collecting abilities of nanofibers prepared from polyvinyl alcohol and calcofluor (PVAC) for an odorological trace collection. Our study revealed that spectrum of odorological traces trapped on nanofibrous PVAC adsorbents, is more stable and reproducible compared to commonly used ARATEXTM. In addition, both PVA and PVAC nanofibers can adhere a large number of traces undetectable by ARATEX. Our results show that functionalization of commonly used adsorbent ARATEXTM with PVA and PVAC nanofibers can vastly increase the accuracy of trace collection and, thus, significantly improve forensic investigations.
