“…Two distinct peaks were observed at 3390 and 3230 cm −1 , indicating the presence of O−H and N−H bonds, respectively. 31,32 The N−H bonds manifest the presence of free amine moieties on the terminals of unpolymerized borazine and triazine structures. However, the O−H bonds can be ascribed to the presence of moisture and oxide contaminants.…”

Screen-printed electrodes (SPEs) have emerged as reliable probes for portable, economical, and practical testing platforms in point-of-care (PoC) applications. Compared to the conventional three-electrode systems, SPEs require significantly less sample volume and omit the cleaning and pre-treatment requirements. This work is focused on amplifying the response signal of SPE using a facile protocol for boron carbon nitride (BCN)-assisted SPE surface functionalization using cyclic voltammetry (CV). To validate the success of the modification, the SPE surface is subjected to chemical and electrochemical characterization using X-ray photoelectron spectroscopy, CV, and differential pulse voltammetry. Ascribed to the BCN's electrocatalytic ability, the modified SPE significantly improves electrochemical activity, with a five-fold increase in current response and an 18 mV potential shift. The fabricated sensing platform demonstrates high sensitivity and selectivity toward quantitative analysis of tryptophan with a detection limit of 36.4 nM. Furthermore, the developed sensor was tested for monitoring TRP levels in complex matrices like food and human body fluids. This proposed approach of electrode modification holds promise for providing swift, precise, and cost-effective means for improving the sensitivity of SPEs for trace level detections required for PoC applications.

“…The d -spacing due to the (002) plane of BCNO is found to be 0.339 nm, which is marginally higher than the characteristic interlamellar spacing of h -BN (0.334 nm). Higher interlamellar spacing implied the carbon and oxygen doping in the h -BN network of BCNO . Notably, a broader hump at a 2θ range of 16–35° along with characteristic diffraction features signified the polycrystalline nature of BCNO and a limited number of lamellae in each sheet of BCNO.…”

Moreover, the amorphous contents associated with oxides and carbon could be accountable for a broader hump-like feature in BCNO.…”

Organic dyes in wastewater jeopardize aquatic ecosystems and biodiversity, besides having several concerns of health hazards. Nanostructured materials of controlled textural features with active surface functionalities are gaining immense interest as effective adsorbents for wastewater treatment. The present work addresses a facile approach to synthesize fibrous aerogel-templated nanostructured boron carbon oxynitride (BCNO). The surface functionalities, structural heterogeneity, crystalline phases, and morphological features of BCNO are probed by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, Raman, X-ray diffraction, and high-resolution transmission electron microscopy analyses. The nanostructured BCNO showed preferential and remarkably high adsorption of cationic dyes with a removal capacity of 1258 mg g −1 for malachite green (MG) dye. The adsorption of MG dye by nanostructured BCNO is carried out at different pH, ionic strength, and temperature to emphasize the influence of environmental factors. The spectroscopic analyses suggested multiple adsorption pathways, viz. electrostatic, π−π, hydrogen, and Lewis acid−base interactions for unprecedentedly higher adsorption of cationic dyes by BCNO. Batch-mode findings promise the potential of nanostructured BCNO for wastewater treatment applications.
