With the miniaturization race, organic field-effect transistor (OFET) devices have gained much attention in recent years due to their advantages of flexibility, light weight, solution processability and low manufacturing cost. However, some inorganic or organic materials are eco-unfriendly. Therefore, in this study, the natural biological proteins collagen hydrolysate acts as dielectric material due to the presence of hydroxyl groups. Cationic surfactant hexadecyltrimethylammonium chloride (CTMA) is added into collagen hydrolysate to form a dielectric layer in bio thin film transistor (BioTFT) device. Experimental results highlight that the collagen-CTMA mixture at 3 wt% (Col-CTMA3) has shown an average mobility of 3.36 × 10⁻² cm²V⁻¹s⁻¹ and an on/off ratio up to 2.7 × 10⁶.1-aminopyrene is embedded into Col-CTMA3 mixture to form Col-CTMA3-1-aminopyrene (Col-CTMA3-AP) mixture to fabricate bio field-effect transistor (BioFET) type memory device. Furthermore, the optimized addition of 1-aminopyrene in the Col-CTMA3-AP mixture for memory device has provided enhanced performances associated to an average mobility of 1.23 × 10⁻² cm²V⁻¹s⁻¹, an on/off ratio up to 5.22 × 10⁵ and a memory window of 13.6 V, as the proportion of 1-aminopyrene increased, the charge-trapping ability of collagen strengthened. Environment effect studies have shown that BioFET memory devices placed under water environment highlight the role of the hydroxyl group for the improved BioFET performance.

随着小型化的竞争，有机场效应晶体管（OFET）器件近年来因其灵活性，轻巧，解决方案可加工性和较低的制造成本而备受关注。但是，某些无机或有机材料对生态不利。因此，在这项研究中，天然生物蛋白胶原蛋白水解物由于存在羟基而充当介电材料。将阳离子表面活性剂十六烷基三甲基氯化铵（CTMA）添加到胶原蛋白水解物中，以在生物薄膜晶体管（BioTFT）器件中形成介电层。实验结果表明，胶原蛋白-CTMA混合物（3 wt％）（Col-CTMA3）的平均迁移率为3.36×10 ^-2 cm ² V ^-1 s ^-1然后将高达2.7×10 ⁶ .1-氨基py的开/关比嵌入Col-CTMA3混合物中，形成Col-CTMA3-1-氨基py（Col-CTMA3-AP）混合物，以制造生物场效应晶体管（BioFET）类型存储设备。此外，在用于存储设备的Col-CTMA3-AP混合物中优化添加1-氨基py提供了与平均迁移率1.23×10 ^-2 cm ² V ^-1 s ^-1有关的增强的性能，开/关比提高至5.22×10 ⁵记忆窗为13.6 V，随着1-氨基py比例的增加，胶原蛋白的电荷俘获能力增强。环境效应研究表明，放置在水环境下的BioFET存储器件突出了羟基对改善BioFET性能的作用。
