摘要

在这项研究中，我们开发了一种基于电场的生物传感器，该传感器带有聚氯乙烯膜，用于精确定量组胺。通过采用实验室的高灵敏度读出电路和先进的双抵消偏移比较器，生物传感器在组胺浓度范围从0.1 μM到300 μM之间表现出强大的线性。该传感器的灵敏度为每μM 4.2个模数（ADC）计数（对应10.25 mV/μM），当组胺与二胺氧化酶（DAO）相互作用时，传感器的响应变化率为61.6 %。相比之下，传统的循环伏安法（CV）仅显示3.8 %的变化。这种微小的差异强调了使用CV方法准确区分组胺水平变化的难度。该生物传感器对组胺的高灵敏度和特异性使其非常适合于现场检查和食品和鱼类市场的便携式使用，有助于早期筛查和减轻组胺相关的健康风险。

Investigation of an electrical-field-based allergen biosensor utilizing selective polyvinyl chloride membranes for histamine detection

In this study, we developed an electrical-field based biosensor with a Polyvinyl Chloride membrane designed for precise histamine quantification. By employing the lab’s high sensitivity readout circuitry in conjunction with an advanced double cancellation offset comparator, the biosensor demonstrates robust linearity across histamine concentrations ranging from 0.1 μM to 300 μM. The sensor exhibits a sensitivity of 4.2 analog-to-digital (ADC) counts per μM (corresponding to 10.25 mV/μM) and detects a 61.6 % variation in response when histamine interacts with diamine oxidase (DAO). In comparison, the traditional cyclic voltammetry (CV) method shows only a 3.8 % change. This minimal difference underscores the difficulty of accurately distinguishing variations in histamine levels using the CV approach. The proposed biosensor's high sensitivity and specificity to histamine make it well-suited for on-site inspections and portable use in food and fish markets, facilitating early screening and mitigation of histamine-related health risks.
