Metal-organic frameworks as porous materials are highly advantageous
over other porous carriers like mesoporous silica or zeolites. They provide
advantages for biomolecule release and their adsorption characteristics
offer many opportunities. Thus, they present high applicability in medicine
and biology. Metal-organic frameworks (MOF) possess appealing structures and usages including high surface area, homogenous structured
nanoscale cavities, and excellent thermal stability. Therefore, they can be
a new sorbent alternative for preparing samples. In the present study, a
MOF fiber application for solid-phase microextraction is reported. The
MOF fiber is in nano size and has a high surface area. 3D and oriented organizations of MOF materials are vital so that they may be utilized as the fiber coating for microextraction in solid-phase for volatile substances in the
medicinal herbs. In order to make Cu-based MOFs into three-dimensional hierarchical nanoarray structures, a coordination replication approach
is created. To this end, Cu(OH)2 nanorod arrays are used as a sacrificial
template. Cu(OH)2 nanorod arrays serving as Cu origin provided coordination with organic ligands for forming MOF crystals and 3D substrate for
supporting Cu-based MOF growth. Following the presentation of the fiber,
essential oils of Satureja hortensis L were determined using GC-MS. Ease
of use, shorter analysis period, inexpensive tools as well as a high rate of
recovery are advantages of the proposed approach compared to ordinary
analysis approaches.
