Metalloporphyrins as sensing material for quartz-crystal microbalance nitroaromatics sensors

Metalloporphyrins based artificial olfactory receptors

“…Coupled with the affinity of metalloporphyrins the performance of the QMB can allow sub-ppm detection of nitroaromatic compounds [14] and androstenone [15]. The study of the response of QMB sensors coated by metalloporphyrin layers shown that metalloporphyrins may interact with volatile compounds with a number of different interaction mechanisms.…”

Detection of organics using porphyrin embedded nanoporous organosilicas

“…The porphyrin was chosen as a result of the minimal challenges presented during synthesis of the PMO materials. Other porphyrins should be investigated to obtain a material that is optimized for nitroenergetics detection (Montmeat et al, 2005;Ni et al, 2004;Takezaki and Tominaga, 2005). Though the presented PMO structures have been demonstrated for adsorption of nitroaromatics previously (Burleigh et al, 2002), incorporation of the porphyrin, a large organic molecule, into the structures has caused a number of changes in material properties.…”

Recursive Least Squares algorithm dedicated to early recognition of explosive compounds thanks to multi-technology sensors

“…In this paper, we propose a multisensor e-nose combining Fluorescence (OPTO) [9], Quartz Crystal Microbalance (QCM) [10] and Surface Acoustic Waves (SAW) [11]. These technologies have been chosen because they have different properties in terms of selectivity, sensitivty and response time.…”
