• insertion of AUR underscores a key mechanistic insight, namely, that effective membrane interaction at low pH values is contingent upon the peptide’s charge modulation, which is critical for endosomal escape processes. This interaction results in localized disruption at the membrane surface, specifically

• FET-based biosensors. Finally, this article proposes intriguing avenues for further research on the topology of FET-based biosensors. Keywords: biomolecule detection; biosensors; charge modulation; dielectric modulation; field-effect transistor; Review 1 Introduction In recent years, biosensor

• . The first transduction mechanism is known as charge modulation, in which charged biomolecule species bind to the surface of the gate insulator and modify the charge density of the channel surface, and thus the surface conductivity by Coulomb interaction. This acts as a gating mechanism, and

• similarly to charge modulated transduction [4]. The dielectrically modulated (DM) FET is considered one of the most promising variants and approaches to field-effect transistor-based biosensors due to its unique ability of detecting both charged and uncharged biological species through charge modulation and

• influences: graphene-promoted high photoluminescence efficiency of RA and RA-induced doping and charge modulation of graphene. The results suggest that low-dimensional hybrid systems, with reciprocal modifications of the constituents’ original properties, may tailor the desired properties in future device

To further investigate the origin of the obstacles we analyzed the time-averaged lateral particle distribution and its correlation to the
