Article Synopsis
- This paper introduces a deep learning method for detecting and classifying organic water pollutants, specifically hydroquinone and benzoquinone, which are tough to distinguish due to similar electroactivity.
- The detection is performed using low-cost, disposable screen-printed electrodes combined with cyclic voltammetry techniques enhanced by nanomaterials like carbon nanotubes, improving sensitivity by about 25 times.
- The analysis results are transformed into RGB images through Gramian angular field transformations, allowing a convolutional neural network to achieve 100% accuracy in classifying the pollutants.
Water pollution is nowadays a global problem and the effective detection of pollutants is of fundamental importance. Herein, a facile, efficient, robust, and rapid (response time < 2 min) method for the determination of important quinone-based industrial pollutants such as hydroquinone and benzoquinone is reported. The recognition method is based on the use of screen-printed electrodes as sensing platforms, enhanced with carbon-based nanomaterials.

However, using SWCNTs in theranostics still requires revealing mechanisms of the SWCNT-mediated effects on cellular functions. Even though rapid and delayed cellular responses can differ significantly and may lead to undesirable consequences, understanding of these mechanisms is still incomplete.

Finding a theranostic agent capable to cure the affected cells and being safe for the healthy ones is the key for successful treatment. Here, we demonstrate that agglomerated single-walled carbon nanotubes (SWCNTs) are promising theranostic agent that enables photo-activated 'cold' destruction of the cancer cells keeping their environment alive.

- The study investigates how an external electric field affects the behavior of single-walled carbon nanotubes (SWCNTs) in glioma cells, focusing on their accumulation, distribution, and clumping.
- C6 glioma cells were treated with SWCNTs and exposed to specific electric pulses, finding that the electric field enhances the uptake of nanotubes by the cells.
- Results showed a significant increase in the number of nanotubes within cell agglomerates after electric field stimulation, suggesting that this method could improve the effectiveness of delivering anticancer drugs while reducing the required doses.
