Abstract
Label-free approaches for molecular diagnostic applications are appealing because of their inherent point-of-care advantages. Nonetheless, technical challenges impose a limit on the use of these methods as will be discussed in this paper. Electrochemical spectroscopic methods, such as impedance and impedance-derived methods, are highly effective in the development of label-free diagnostic assays, but they require careful control of the dynamics of the sensing interface. We herein report the strength and challenges of the current methodologies associated with the applications of impedance and impedance-derived methods by focusing on their principles of operation. We demonstrate that the uses of their potentialities are not based on the know-how of these methods, but on how to combine the spectroscopic features with the required chemical design for the associated sensing interfaces. Predominantly, we illustrate how to use the resistive and capacitive terms of the interface to improve its sensitivity to the target. For instance, with the proper signal amplification strategy, limitations related to target-to-receptor size ratio can be overcome. The target-to-receptor ratio is one of the difficulties that we use as an example to illustrate how the sensing of an electric signal can be improved by controlling the properties of the interface on the nanometer scale.

Abstract
This paper describes the development of a "diffusion-to-surface" ratiometric graphene electrosensor for the selective detection of live cells and pathogens that highly express mannose-binding proteins (MBPs). MBPs have been implicated in many pathological processes and are identified on specific types of bacteria. Consequently, MBPs are a promising biomarker for targeted disease diagnosis and therapy. Here, we develop a unique electrosensor that features a ratiometric voltammetric signal for the selective probing of MBPs. Self-assembly of mannosyl anthraquinone (AQ) to a graphene oxide-decorated screen-printed electrode produces the sensor with an inherent surface-controlled voltammetric signal. Subsequently, addition of a redox probe (RP) imparts the system with a diffusion-controlled current, thus enabling a ratiometric sensing rationale for which AQ serves as a reference. While the reference current is hardly compromised by adding analytes, RP exhibits a concentration-dependent current quenching on addition of mannose-selective lectins over other proteins. Importantly, this ratiometric electrosensor has proven to be applicable for the ratiometric probing of alternatively activated macrophages and a Gram-negative bacterium highly expressing MBPs, but shows minimal response to a series of control live cells and bacteria without mannose receptor expression.
