“…The ability to detect a wide range of illicit drugs, such as heroin, cocaine, methamphetamine and mephedrone, is, therefore, a significant challenge whose overcoming will bring great benefits to society. 4,5 The successful detection of such drugs has become a crucial priority to reduce threats and risks to public health, [6][7][8][9][10] which cause serious damage, such as respiratory, cardiac, renal damage and also mental health problems such as violence, depression, anxiety and hallucinations. 11,12 In order to design sensitive, fast, portable, and low-cost sensing nanodevices, it is necessary to develop new nanomaterials and device concepts, and devise new plans and strategies to control, manage, and develop precise sensor chips.…”
