A single molecule sensor for several analytes is indeed desired by the scientists around the world due to obvious advantages. In this report we present a new class of Lophine incorporated azo dyes that has capacity of differential colorimetric detection of several metal ions. Interestingly the sensor was found to have pH dependent selective response towards several metals.

The utilization of dual-working-electrode mode of interdigitated array (IDA) electrodes and other two-electrode systems has revolutionized electrochemical detection by enabling the simultaneous and independent detection of two species, accompanied by the exhibition of unique characteristics. In contrast to conventional dual-potential electrodes, such as the rotating ring disk electrodes (RRDE), IDA electrodes demonstrate analogous yet vastly improved performance, characterized by remarkable collection efficiency and sensitivity. Notably, due to the distinctive microscale structure of IDA electrode, the special "feedback" effect makes IDA a unique signal amplifier.

Access to synthetic oligonucleotides is crucial for applications in diagnostics, therapeutics, synthetic biology, and nanotechnology. Traditional solid phase synthesis is limited by sequence length and complexities, low yields, high costs and poor sustainability. Similarly, polymerase-based approaches such as in vitro transcription and primer extension reactions do not permit any control on the positioning of modifications and display poor substrate tolerance.

The porous structure is crucial in bone tissue engineering for promoting osseointegration. Among various structures, triply periodic minimal surfaces (TPMS) -Gyroid has been extensively studied due to its superior mechanical and biological properties. However, previous studies have given limited attention to the impact of unit cell size on the biological performance of scaffolds.
