Nanostructured Thin Films Enhancing the Performance of New Organic Electronic Devices: Does It Make Sense?

Electronics have evolved significantly with the development of semiconductor materials and devices, with emerging areas such as organic and flexible electronics showing great promise, particularly in applications such as wearable devices and environmental sensors. Since the discovery of conducting polymers in the late 1970s, organic electronics have paved the way for innovations such as organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), and organic solar cells (OPVs). Recent advances have focused on nanostructuring techniques to enhance device properties, such as charge mobility and luminescence efficiency.

Selective Detection of Paraquat in Adulterated and Complex Environmental Samples Using Raman Spectroelectrochemistry.

Growing demand for pesticides has created an environment prone to deceptive activities, where counterfeit or adulterated pesticide products infiltrate the market, often escaping rapid detection. This situation presents a significant challenge for sensor technology, crucial in identifying authentic pesticides and ensuring agricultural safety practices. Raman spectroscopy emerges as a powerful technique for detecting adulterants.

Investigating layer-by-layer films of carbon nanotubes and nickel phthalocyanine towards diquat detection.

The indiscriminate use of pesticides makes us susceptible to the toxicity of these chemical compounds, which may be present in high quantities in our food. It is crucial to develop inexpensive and rapid methods for determining these pesticides for government control or even for the general population. In this study, we investigated the fabrication of self-assembled LbL films using multi-walled carbon nanotubes (MWCNT) and nickel tetrasulphonated phthalocyanine (NiTsPc) as an electrochemical sensor for the herbicide Diquat (DQ).
