Monitoring of biomolecules in food plays a crucial role in safeguarding human health. Prevalent biomolecule monitoring systems are constructed predominantly from rigid materials and have inherent limitations in detection capabilities. Wearable sensors have increasingly captured attention, significantly propelling the evolution of biomolecular detection process. However, most studies concentrate on the single sensing core that catalyze individual biomolecule, primarily for healthcare applications. This study introduces multiple biomolecules sensing platform based on a single-sensor core of hollow Prussian blue (h-PB), enabling efficient food detection. By utilizing varied potentials and leveraging excellent conductivity of MXene, this platform selectively and effectively tracks biomolecules including hydrogen peroxide, ascorbic acid, and glucose. Notably, the origin of electrochemical activity in this sensing system is demonstrated. This research provides a novel pathway for multi-sensing platforms design, leveraging a single catalytic core as active layer, thereby offering a promising trajectory for wearable electronics endowed with enhanced sensing capabilities.
食品中生物分子的监测在保障人类健康方面起着至关重要的作用。普遍的生物分子监测系统主要由刚性材料构建而成，在检测能力方面存在固有局限性。可穿戴传感器越来越受到关注，极大地推动了生物分子检测过程的发展。然而，大多数研究集中在催化单个生物分子的单一传感核心上，主要用于医疗保健应用。本研究介绍了基于空心普鲁士蓝（h-PB）单传感器核心的多生物分子传感平台，可实现高效的食品检测。通过利用不同的电位并借助MXene的优异导电性，该平台能够选择性且有效地追踪包括过氧化氢、抗坏血酸和葡萄糖在内的生物分子。值得注意的是，还证明了该传感系统中电化学活性的来源。本研究为多传感平台设计提供了一条新途径，利用单个催化核心作为活性层，从而为具有增强传感能力的可穿戴电子产品提供了一条有前景的发展轨迹。
