A medical device which can include a graphene varactor (100). The graphene varactor (100) can include a graphene layer (108a, 108b) and a self-assembled monolayer disposed on an outer surface of the graphene layer through pi-pi stacking interactions. The self-assembled monolayer can provide a Langmuir theta value of at least 0.9. The self-assembled monolayer can include polycyclic aromatic hydrocarbons, tetraphenylporphyrins or derivatives thereof, metallotetraphenylporphyrins, or aromatic cyclodextrins. Corresponding fabrication method and a method of detecting an analyte in a gaseous sampleof a patient with the medical device are also disclosed. 一种医疗装置，其可以包括石墨烯变容二极管(100)。所述石墨烯变容二极管(100)可以包括石墨烯层(108a，108b)和通过π-π堆积相互作用设置在所述石墨烯层的外表面上的自组装单层。所述自组装单层可以提供至少0.9的朗缪尔θ值。所述自组装单层可以包括多环芳烃、四苯基卟啉或其衍生物、金属四苯基卟啉或芳族环糊精。还披露了相应的制造方法和利用所述医疗装置检测患者的气态样本中的分析物的方法。
