Um quimiossensor potenciométrico para determinação seletiva de sertralina foi desenvolvido, baseado na técnica de impressão molecular. O polímero impresso molecularmente foi sintetizado através da polimerização por precipitação, usando hidrocloreto de sertralina como molécula molde, ácido metacrílico como monômero funcional e dimetacrilato de etileno glicol como um agente de ligação cruzada. O sensor foi desenvolvido pela dispersão das partículas de polímero impressas na sertralina, em plastificante dibutil sebacato e incorporação em matiz de poli(cloreto de vinila). As características do sensor proposto foram avaliadas medindo a resposta do potencial para hidrocloreto de sertralina, no intervalo de 1,0 µmol L -1 a 10 mmol L -1 com resposta Nernstiniana de 57,7 mV década -1 e um limite de detecção de 0,8 µmol L -1 . Os coeficientes de seletividade potenciométrica do sensor proposto foram avaliados e exibiram boa seletividade para sertralina com relação a outros antidepressivos. Foi usado como eletrodo indicador na determinação potenciométrica de sertralina em comprimidos e fluidos biológicos.A potentiometric chemosensor for selective determination of sertraline was developed based on the molecular imprinting technique. The molecularly imprinted polymer was synthesized by precipitation polymerization, using sertraline hydrochloride as a template molecule, methacrylic acid as a functional monomer and ethylene glycol dimethacrylate as a cross-linking agent. The sensor was developed by dispersing the sertraline imprinted polymer particles in dibutyl sebacate plasticizer and embedding in poly(vinyl chloride) matrix. Characteristics of the proposed sensor were evaluated by measuring the potential response to sertraline hydrochloride in the range from 1.0 µmol L -1 to 10 mmol L -1 with a near Nernstian response of 57.7 mV decade -1 and a limit of detection of 0.8 µmol L -1 . The potentiometric selectivity coefficients of the proposed sensor were evaluated and it exhibited good selectivity to sertraline with respect to the other antidepressants. It was used as indicator electrode in potentiometric determination of sertraline in tablets and biological fluids.

Thiacalixarenes, a subclass of "third generation" calixarenes, exhibit many interesting features such as enlarged ring size, facile chemical modification, and metal complexation due to the presence of bridging sulfur atoms. The thiacalixarene scaffold is a unique host with vast possibilities for functionalization not only at the upper and lower rim but also at the bridging sulfide groups. Modified thiacalixarenes have been used for many applications such as the detection and separation of biologically important cations, anions, and bio-analytes, mimicking molecular logic gates and devices, and synthesis of self-assembled coordination cages, multinuclear complexes, magnetic materials and luminescent materials. This review article summarizes recent developments in the derivatization methods of thiacalixarenes and their utilization in various applications.

Memantine hydrochloride is one of the first novel class medications for treatment of Alzheimer's disease. In this work, a biomimetic potentiometric sensor, based on a non-covalent imprinted polymer, was fabricated for the recognition and determination of memantine in pure drug and tablet pharmaceutical form. The molecularly imprinted polymer was synthesized by precipitation polymerization, using memantine hydrochloride as a template molecule, methacrylic acid as a functional monomer, and ethylene glycol dimethacrylate as a cross-linking agent. The sensor was developed by dispersing the memantine imprinted polymer particles in dibutyl sebacate plasticizer and embedding in poly(vinyl chloride) matrix. The wide linear range (10(-5) -10(-1) M), with a near Nernstian response of 57.4 mV/decade, a limit of detection 6.0 × 10(-6) M, fast response time (~15 s) and a satisfactory long-term stability (4 months) are characterizations of the proposed sensor. The sensor showed a high selectivity and a sensitive response to the template in aqueous system. The standard electrode potentials were determined at different temperatures and used to calculate the isothermal coefficient of the electrode. It was used as indicator electrode in potentiometric determination of memantine in pharmaceutical formulations.
