由于不健康的饮食习惯,肥胖症已经引起了我们的关注。瘦素作为一种主要在脂肪组织中产生的多肽激素,是与肥胖疾病相关的生物标志物。在这里,我们提出了一种电化学生物传感器,使用还原的氧化石墨烯-金纳米材料(rGO-Au)修饰玻璃碳电极(GCE)和生物纳米胶囊ZZ(ZZ-BNC)来垂直定位抗体以检测瘦素。瘦素浓度在0.001~1000npg/m L范围内与峰面积呈良好的线性关系,检出限为0.00087 pg/m L。与已报道的瘦素传感器相比,该传感器具有检测下限低、选择性高、抗干扰性好等特点。值得注意的是,我们的生物传感器能够检测饮食诱导的肥胖小鼠模型中的瘦素,与酶联免疫吸附试验(ELISA)的结果非常一致。使用该生物传感器对不同体重指数(BMI)的人也显示了不同的检测结果。因此,我们的研究表明,基于定向抗体固定化的电化学生物传感器是检测实际样品中瘦素的有效平台,在肥胖疾病评估中具有广泛的应用前景。
Obesity diseases have drawn our attention attributing to unhealthy dietary habit. Leptin, as a peptide hormone produced primarily in adipose tissue, is a biomarker associated with obesity diseases. Here, we presented an electrochemical biosensor used reduced graphene oxide-gold nanomaterials (rGO-Au) to modify the glassy carbon electrode (GCE) and bionanocapsule-ZZ (ZZ-BNC) to vertically orient the antibody for detection of leptin. The linear correction curves of leptin concentration ranged from 0.001 to 1000 pg/mL with a low detection limit (0.00087 pg/mL). Compared with reported leptin sensors, the biosensor displayed low detection limit, higher selectivity and anti-interference. Notably, our biosensor enabled to detect the leptin in diet-induced obese mouse model with a good agreement of enzyme linked immunosorbent assay (ELISA). The distinct detection results also showed in human with different body mass index (BMI) using the biosensor. Therefore, our study demonstrated that the oriented antibody immobilization based electrochemical biosensor is an effective platform for detection of leptin in actual samples and may have broad applications in assessment of obesity diseases.
