Nypa fruticans-assisted green-synthesized gold nanoparticles for an enhanced electrochemical formaldehyde sensor based on fish albumin composite T.P.H. Hutapea, M.S. Lembang, A. (Al-Chairul) Huda, Asranudin, D.P. Dewi, et al. Global Journal of Environmental Science and Management, 2026 BACKGROUND AND OBJECTIVES: The need for sustainable, rapid, and cost-effective electrochemical sensors for formaldehyde monitoring is increasing. Traditional noble metal nanoparticle synthesis often uses hazardous chemicals. This study pioneered the green synthesis of gold nanoparticles using Nypa fruticans leaf extract. The core objectives of the study were to develop a highly sensitive and selective electrochemical formaldehyde sensor by integrating these novel, green-synthesized gold nanoparticles into a conductive fish albumin composite matrix on a gold electrode.METHODS: Gold nanoparticles were created using a simple heating and stirring method with Nypa fruticans leaf extract, utilizing its natural metabolites. Formation was confirmed using ultraviolet-visible, fourier transform infrared, x-ray diffractometer, Particle size analyzer, field emission-scanning electron microscope, and High-resolution transmission electron microscopy analyses. The sensor probe, incorporating the gold nanoparticles into a snakehead fish albumin-paraffin composite, was fabricated and applied to a gold wire electrode. Its electrochemical performance was evaluated Electrochemical sensor; Fish albumin; Formaldehyde detection; Green synthesis; Gold nanoparticles (AuNps).against a 1 millimolar formaldehyde solution using cyclic voltammetry. Key parameters, including optimal potential of hydrogen, reaction kinetics, linear dynamic range, limit of detection, and selectivity against common interferents (methanol, ethanol, glucose, glycerol), were investigated.FINDINGS: Characterization confirmed the successful formation of crystalline, face-centered cubic gold nanoparticles, predominantly spherical, with small sizes ranging from 2 to 8 nanometers, highlighting the efficacy of the green synthesis method. The gold electrode modified fish albumin and gold nano particles exhibited significantly enhanced anodic peak current at +1.13 volt compared to control electrodes (Paraffin-modified gold electrodes and fish albumin-modified gold electrodes), demonstrating the superior catalytic and conductive properties imparted by the gold nanoparticles. Optimal sensing performance was achieved under acidic conditions with a pH value of 1. The electrode displayed a broad linear dynamic range from 1 micromolar to 50 millimolar. Critically, the sensor has good sensitivity and selectivity with an ultra-low limit of detection of 0.177 micromolar, the lowest reported among the compared electrodes in the literature, especially the albumin-modified gold electrode, which has a detection limit of 4.07 micromolar for formaldehyde.CONCLUSION: Environmentally friendly synthesis of gold nanoparticles uses Nypa fruticans extract, providing a sustainable, cost-effective method. The resulting gold electrode, modified with fish albumin and gold nanoparticles, created an electrochemical sensor with exceptional performance, high selectivity, and an ultralow detection limit for formaldehyde detection.
Structural and physicochemical properties of microcrystalline cellulose isolated from waste paper pulp using citric acid hydrolysis Holilah, Agus Wedi Pratama, Asranudin, Nanang Masruchin, Widyastuti, Didik Prasetyoko, Nur Fitriana, Aminatun Nisa, Victor Feizal Knight, Mohd Nor Faiz Norrrahim Results in Chemistry, 2026 Microcrystalline cellulose (MCC) was isolated from waste paper pulp using an eco-friendly approach based on citric acid hydrolysis, offering a green alternative to conventional mineral acids. This study investigated the influence of citric acid concentration (3 M, 4 M, and 5 M) on the resulting MCC's properties, followed by purification and bleaching. The optimal condition was achieved with 4 M citric acid (MCC4), which produced MCC with a high crystallinity index (80.2%), a substantial yield (78.1%), and excellent thermal stability (T peak = 350.5 °C). The isolated rod-shaped MCC from paper pulp showed the particle dimension in the average of 14.98 μm with a narrow distribution. A comprehensive physicochemical analysis demonstrated that the properties of the resulting MCC (including density, pH, and ash content) were highly comparable to commercial Avicel PH-101. Notably, the prepared MCC4 exhibited superior functional properties, specifically higher water holding capacity (2.95 g/g) and oil holding capacity (3.05 g/g). The findings demonstrate that citric acid hydrolysis is a highly effective, non-corrosive, and environmentally friendly alternative to traditional mineral acid methods for MCC production. This research provides a viable pathway for transforming paper waste into high-value bioproducts suitable for pharmaceutical, food, and composite applications, contributing to a circular bio-economy. • An eco-friendly citric acid hydrolysis method was applied to waste paper pulp. • 4 M citric acid concentration optimized the yield (78.1%) and crystallinity (80.2%). • The produced MCC exhibited excellent thermal stability (T peak = 350.5 °C). • Physicochemical properties of the resulting MCC were comparable to Avicel PH-101. • Water (WHC) and oil (OHC) holding capacities were superior to the commercial standard.
Recent advances in the roles of spent coffee grounds as multifunctional fillers in biopolymer-based composites: a review Haya Fathana, Muhammad Iqbal Hidayat, Asranudin, Agus Wedi Pratama, Victor Feizal Knight, Mohd Nor Faiz Norrrahim, Dina Wahyu Indriani, Febio Dalanta South African Journal of Chemical Engineering, 2026 • Utilized SCG as multifunctional fillers that improved the performance of biofilms • Comparing biopolymer matrices reveals varied interactions shaping their properties • Lignin, cellulose, and phenolics in SCG enhance strength, UV-shielding, and antioxidant properties • Applying circular bioeconomy principles highlights SCG as a sustainable low-cost filler Spent coffee grounds (SCG), a prevalent byproduct of the global coffee industry, represent a significant lignocellulosic resource with considerable economic potential. Although the use of SCG as a filler in biopolymer-based films is increasing, a comprehensive evaluation of its multifunctional activities in diverse polymeric matrices is limited. This review aims to critically integrate current studies to elucidate how SCG composition and film preparation strategies govern the structural and functional performance of biopolymer films, demonstrating that SCG can perform multiple roles as a reinforcing, barrier-enhancing, and bioactive filler across a wide range of biopolymer matrices, enabling diverse functional and application-specific performances. SCG incorporation in biopolymer matrices such as chitosan, pectin, carboxymethyl cellulose (CMC), starch, gelatin, and polylactic acid (PLA) is discussed with emphasis on correlations between SCG composition, film processing, and resulting structural and functional properties. The findings indicate that SCG acts as a dual-function filler by enhancing film structure while imparting bioactive functionalities such as antioxidant activity and UV-blocking capability. Reported data show that SCG loadings (<10 wt%) can increase tensile strength by approximately 10–40% while improving UV shielding and antioxidant performance. However, excessive SCG content often reduces elongation at break, increases film brittleness, and compromises optical transparency, highlighting the importance of filler optimization and matrix compatibility. Therefore, this review provides a comprehensive and application-oriented perspective on the multifunctional utilization of SCG as a sustainable filler, highlighting matrix-dependent advantages, structure property relationships, and performance trade-offs that enable its tailored use in active, biodegradable, and functional packaging as well as related film-based applications.
