Xu XY, Yan B, Lian X. Wearable glove sensor for non-invasive organophosphorus pesticide detection based on a double-signal fluorescence strategy. NANOSCALE 2018; 10:13722-13729.

Abstract
A wearable glove-based sensor has been developed for non-invasive organophosphorus pesticide (OP) monitoring via the fluorescent detection technology. The new "lab-on-a-glove" device integrates a flexible host material (CMC aerogel) and two fluorescent centers (EuMOFs for red and nanosized CDs for blue emissons). After characterizing the performance and stability of the sensor, qualitative and quantitative OP detections are successfully conducted on the surfaces of different agricultural products using swipe collection. The real-time detection system offers considerable advantages such as rapid response (30 s) due to the porous structures of CMC aerogel and MOFs, detection with the naked eye (the red to blue emission transition corresponds to an increase in the OP concentration) and high sensitivity (R2 = 0.99529, LOD = 89 nM) owing to the double-signal sensing strategy in which EuMOFs are the working fluorescence center and CDs are the reference fluorescence center. Compared with other OP detection methods, our strategy of using wearable device with the ratiometric fluorescence method leads to a convenient and reliable detection process for OP analysis. Also, considering its cost advantage, the glove-based sensor holds promise for practical applications in food safety and security.

Abstract
In the present study, we report a highly sensitive, rapid and low cost colorimetric monitoring of malathion (an organophosphate insecticide) employing a basic hexapeptide, malathion specific aptamer (oligonucleotide) and silver nanoparticles (AgNPs) as a nanoprobe. AgNPs are made to interact with the aptamer and peptide to give different optical responses depending upon the presence or absence of malathion. The nanoparticles remain yellow in color in the absence of malathion owing to the binding of aptamer with peptide which otherwise tends to aggregate the particles because of charge based interactions. In the presence of malathion, the agglomeration of the particles occurs which turns the solution orange. Furthermore, the developed aptasensor was successfully applied to detect malathion in various water samples and apple. The detection offered high recoveries in the range of 89-120% with the relative standard deviation within 2.98-4.78%. The proposed methodology exhibited excellent selectivity and a very low limit of detection i.e. 0.5pM was achieved. The developed facile, rapid and low cost silver nanoprobe based on aptamer and peptide proved to be potentially applicable for highly selective and sensitive colorimetric sensing of trace levels of malathion in complex environmental samples.

Abstract
A novel detection platform with high malathion specificity has been developed, which operates based on the signal response in the fluorescence of CdTe@CdS quantum dots (QDs). The designed nanoprobe comprises of QDs, poly(N-(3-guanidinopropyl)methacrylamide) homopolymer (PGPMA) and malathion specific aptamer. The interaction of aptamer with malathion results in switching off of the fluorescence signal of the probe due to the availability of the cationic polymer, which causes quenching of the QDs. However, in the absence of malathion, the polymer interacts with the aptamer, via electrostatic interactions thereby rendering the fluorescence of QDs unaffected. The assay exhibited excellent sensitivity towards malathion with a detection limit of 4pM. A logarithmic correlation was observed in a wide range of malathion concentrations from 0.01nm to 1μM, facilitating the potential of proposed assay in the quantitative determination of the analyte of interest. The selectivity of the designed probe was confirmed in the presence of various pesticides, commonly employed in agricultural fields.

Abstract
Porous carbons in the separation sciences occupy an important niche owing to their unique retention characteristics, chemical stability and the ability to control pore structure through template strategies. However, these same synthetic processes utilise oil-based carbonising resins and high temperature, energy-intensive pyrolysis steps to ensure the carbon product has pore-size regularity, minimal micropore content and homogeneous surface chemistry. This chapter will primarily focus on the development of porous carbons for application as chromatographic stationary phases. Discussion will cover the unique characteristics of the porous carbon retention mechanism and its application in separating a broad range of analyte classes. The chapter then moves on to describe the current disadvantages in the manufacture of commercially available carbon phase and then highlight recent efforts aimed at the development of alternative porous carbon stationary phases derived from sustainable carbon precursors.

Abstract
The possibility to utilize nanocomposite films as easy-to-handle surfaces for surface assisted laser desorption ionization-mass spectrometry (SALDI-MS) of small molecules, such as pharmaceutical compounds, was evaluated. The signal-to-noise values of acebutolol, propranolol and carbamazepine obtained on the nanocomposite surfaces were higher than the values obtained on plain PLA surface showing that the nanoparticles participate in the ionization/desorption process even when they are immobilized in the polymer matrix. The advantages of nanocomposite films compared to the free nanoparticles used in earlier studies are the ease of handling and reduction of instrument contamination since the particles are immobilized into the polymer matrix. Eight inorganic nanoparticles, titanium dioxide, silicon dioxide, magnesium oxide, hydroxyapatite, montmorillonite nanoclay, halloysite nanoclay, silicon nitride and graphitized carbon black at different concentrations were solution casted to films with polylactide (PLA). There were large differences in signal intensities depending on the type of drug, type of nanoparticle and the concentration of nanoparticles. Polylactide with 10% titanium oxide or 10% silicon nitride functioned best as SALDI-MS surfaces. The limit of detection (LOD) for the study was ranging from 1.7 ppm up to 56.3 ppm and the signal to noise relative standard deviations for the surface containing 10% silicon nitride was approximately 20-30%. Scanning electron microscopy demonstrated in most cases a good distribution of the nanoparticles in the polymer matrix and contact angle measurements showed increasing hydrophobicity when the nanoparticle concentration was increased, which could influence the desorption and ionization. Overall, the results show that nanocomposite films have potential as surfaces for SALDI-MS analysis of small molecules.
