Summary: A modern optical sensor based on environmentally friendly molecularly imprinted polymer coated on silica-carbon quantum dots was developed for rapid and efficient detection of the common chemical contaminant indoxacarb in environmental and biological samples. The sensor showed a linear relationship between fluorescence quenching effect and increased indoxacarb concentration in the range of 4-102 nM, with a detection limit of 1 nM and good precision. The applicability of the sensor for indoxacarb quantification in samples was verified with high recoveries and low relative standard deviation.

Summary: In this study, a molecularly imprinted polymer (MIP)-based electrochemical sensor with enhanced sensitivity for the detection of cortisol was developed. The sensor utilized a nano gold-doped poly-o-PD film, which facilitated charge transfer and blocked the charge transfer when cortisol occupied the binding cavities, resulting in enhanced detection response and sensitivity. The sensor exhibited high affinity and selectivity towards cortisol and showed promising potential for point-of-care testing applications.

Summary: In this study, a molecularly imprinted polymer (SPCC-CSL-MIPs) with specific selectivity for celastrol was successfully prepared using a porous cellulose microsphere carrier based on traditional Chinese medicine waste. The structure and adsorption performance of SPCC-CSL-MIPs were investigated and analyzed using various techniques. Experimental results showed that the SPCC-CSL-MIPs had a high adsorption capacity of 14.38 mg/g and a good imprinting factor of 2.36. The prepared SPCC-CSL-MIPs were able to maintain a stable adsorption performance of 77.98% after 5 cycles. These results indicate that SPCC-CSL-MIPs can be used as an excellent adsorbent for efficient celastrol enrichment and separation from complex matrices and significantly increase the content of celastrol in T. wilfordii extract from 0.46% to 3.87%.

Summary: Redox-active MIP-Gly NPs were developed by incorporating ferrocenylmethyl methacrylate into the synthesis process, enabling them to selectively determine glyphosate without the need for redox probe. MIP-Gly NPs synthesized using allylamine and squaramide-based monomers exhibited the highest selectivity. The MIP-Gly NPs modified Pt-SPEs were characterized using differential pulse voltammetry and electrochemical impedance spectroscopy, with changes in the oxidation peak of the ferrocenyl moieties serving as the analytical signal. The chemosensor showed a low limit of detection and a wide linear dynamic concentration range for glyphosate, allowing successful detection in spiked river water samples.

Summary: Molecularly imprinted polymer (MIP) is a synthetic material that mimics the natural antibody-antigen system and is suitable for use in electrochemical sensors. However, the irregular shape and slow electron transfer rate of MIP limit the sensitivity and conductivity of the sensors. The integration of nanomaterials improves the sensing and recognition capability of MIP sensors.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

Summary: This study synthesized Cs2NaInCl6 nanocrystals co-doped with Sb3+ and Tb3+ ions as probes for copper ions detection in lubricating oil. The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
