Summary: A colorimetric sensor based on a redox reaction between AuCl4- ions and reducing sugars was developed, with different sugars showing varied reaction rates and LOD values. The sensitivity of the sensor can be enhanced by prolonging the reaction time, and the linear range for different sugars differs, with distinct LOQ values observed.

Summary: A diaminotriazine (DAT)-containing polydiacetylene (PDA-DAT) colorimetric sensor was developed for selective detection of thymine and oligothymidine. PDA-DAT undergoes a color change in the presence of thymine and oligothymidine due to hydrogen bonding interactions, resulting in absorption spectral shift and corresponding color change. The detection limits for thymine and oligothymidine are 12.6 nM and 14.6 nM, respectively. This study provides a foundation for the design of colorimetric sensors for thymine and oligothymidine.

Summary: The present work reports the synthesis, characterization, and antimicrobial activities of adipic acid-capped silver nanoparticles (AgNPs@AA) and their utilization for selective detection of Hg2+ ions in an aqueous solution. The synthesized AgNPs@AA were characterized by various techniques and showed potential antimicrobial activity against clinically isolated pathogens. These AgNPs selectively interacted with Hg2+ ions in the solution and a calibration curve was constructed for the detection of Hg2+ ions. The nano-probe demonstrated a rapid response time and low detection limit.

Summary: Gold nanoparticles were designed and constructed to decompose hydrogen peroxide and reduce metal ions, with the ability to indirectly detect mercury (II) by forming an amalgam. The colorimetric detection of mercury (II) ions was achieved by the oxidation of 3,4-diaminotoluene, allowing for determination within a reasonable range. This method was found to be advantageous for monitoring mercury (II) levels in real water samples, providing a simple solution for areas lacking high-tech technology.

Summary: In this work, a simple visual and rapid colorimetric strategy for detecting Hg2+ based on gold nanoparticles modified with sulfadiazine was proposed and characterized by TEM, DLS, XRD, and UV-vis. The color of the solution changed from red to blue gray with increasing Hg2+ concentration due to the aggregation of AuNPs with anti-interference. The LOD was 1.0 μg/mL by the naked eye and 0.071 μg/mL by UV-vis spectroscopy, with a good linear relationship (R2 = 0.994), indicating the potential use of AuNPs modified with sulfadiazine for quantitative determination of Hg2+. The SDZ-AuNPs detection system exhibited excellent selectivity for Hg2+ compared to other interferents in cosmetics, suggesting its successful application in real sample detection of Hg2+.
