“…These authors reported that the optical fibre probes gave a linear response over a concentration range of 0.02 M-0.96 M, by recording surface plasmon resonance spectra in which a significantly large shift was observed in presence of target molecules. Cennamo et al (2013Cennamo et al ( , 2014Cennamo et al ( , and 2015 reported a series of studies including combinations of optical fibres with surface plasmon resonance and MIPs.…”

“…MIP/surface plasmon resonance biosensors for trinitrotoluene and Lnicotine were built using both tapered and non-tapered optical fibres and then their sensing performances were compared (Cennamo et al, 2013 and. In addition, this group investigated the effect of gold nanoparticles on sensor performance by using five-branched gold nanostars added into the MIP layer (Cennamo et al, 2015).…”

“…2 Overcoming the need for reactions, a detection limit of 50 μM has been attained, 18 which is in the order of 10 3 times greater than the lower detection limit previously achieved. 2 The differences in the detection limits in these works 2,17,18 are attributed to the differences in the MIP preparations. Voltammetric-MIP sensors for TNT detection have shown high sensitivity and moderate selectivity, via chemically modified electrodes.…”

The development of sensors capable of efficient 2,4,6-trinitrotoluene detection is evolving into an important research field due to mounting threats to public safety. Molecularly imprinted polymers are receiving intensifying attention as potential recognition elements. Currently, there is limited understanding as to how the solvent impacts the crucial complexation stage in imprinted polymer production. Here, we investigate whether solvent interactions during the complexation stage should be considered in the optimal design of such sensors. The approach adopted uses molecular dynamics to simulate the interactions between all relevant molecules in the pre-polymerization mixture with different porogenic solvents: pure acetonitrile, dimethyl sulfoxide, water, and binary mixtures at different compositions of the former two. Molecular dynamics provides an excellent opportunity to gain an accurate insight into the behaviour of the porogen molecules with the target molecule and functional monomers. The results showed conclusive evidence towards solvent interactions impacting the complex's quality in the studied system. A porogen mixture, acetonitrile : dimethyl sulfoxide, of 75 : 25 molar ratio is suggested for optimal trinitrotoluene and methacrylic acid complexation.

“…Therefore, fast and reliable detection of trace TNT has attracted considerable attentions [5]. Various analytical techniques, including gas chromatography [6,7], high performance liquid chromatography [8,9], voltammetry [10,11], ion mobility spectrometry [12,13], mass spectrometry [14,15], energy dispersive X-ray diffraction [16,17], surface enhanced Raman spectroscopy [18,19], and surface plasmon resonance [20][21][22], just name a few, have been applied in the detection of trace amounts of TNT. These techniques are all effective, but the requirement of complicated analytical instruments, lengthy and tedious operation procedures of these methods exclude their application in on-site analysis, especially in emergencies.…”
