Universidad de Zaragoza (orcid)0000-0001-9897-6527 Explosives Detection by Array of Si µ -Cantilevers Coated with Titanosilicate-Type Nanoporous Materials 2016 Access copy available to the general public Unrestricted An array comprising four Si µ -cantilevers coated with nanoporous functionalized ETS-10 crystals sub-micrometric in size has been developed as a multisensing platform for explosives recognition in vapor phase. The detection capabilities of the proposed device have been tested for common taggants such as 1-methyl-2-nitro-benzene (o-MNT)] and explosives (commercial detonation cord, a plastic tube filled with pentaerythritol tetranitrate (PETN); and C-4, a mixture of cyclotrimethylenetrinitramine (RDX), binders and plastifiers). The general strategy for the detection of explosives in vapor phase is based on the characteristic fingerprint each one produces as a result of the dissimilar chemical interactions between the ETS-10 coated µ -cantilevers and the target molecules emanating from the explosives and swept by ambient air. A portable lock-in amplifier has been implemented to exploit the truly benefits of the array in terms of portability, reduced size, and energy consumption. Such low-power electronic interface is capable of creating the excitation signal as well as obtaining the response values of four resonating µ -cantilevers simultaneously. The resulting sensing platform has successfully been applied for the o-MNT, PETN, and RDX detection at trace level. info:eu-repo/grantAgreement/ES/MICINN/CTQ2010-19276 info:eu-repo/grantAgreement/ES/MICINN/CTQ2013-49068 info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2012-30802 info:eu-repo/semantics/openAccess by-nc-sa http://creativecommons.org/licenses/by-nc-sa/3.0/es/ 2.512 2016 INSTRUMENTS & INSTRUMENTATION 12 / 58 = 0.207 2016 Q1 T1 PHYSICS, APPLIED 48 / 147 = 0.327 2016 Q2 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 85 / 260 = 0.327 2016 Q2 T1 0.654 2016 Electrical and Electronic Engineering 2016 Q1 Instrumentation 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Almazán, F.
