Development of a Graphene SG-FET aptasensor able to detect attomolar concentrations of hepatitis C virus core protein

Biosensors based on graphene field-effect transistors have become a promising tool for detecting a broad range of analytes. However, they lack the stability and reproducibility required to step into biotechnological and biomedical applications. ESISNA group has used a promising physical graphene functionalization protocol which allows atomically-precise highly-controlled covalent functionalization, preserving…

The influence of reaction conditions on the growth of MOFs on surfaces

The importance of the reaction conditions has been confirmed in this study, where following an on-surface synthesis approach on the same surface and with the same precursor, two different metal-organic frameworks were obtained. The distinction comes from the different synthesis protocol of the controlled growth of both metal-organic nanostructures. Thus,…

Why individual heptagonal rings are not stable on surfaces? (Nanomaterials 2022)

Graphene nanoribbons, GNRs, – narrow stripes of graphene – are predicted to exhibit attractive electronic properties for the fabrication of nanoscale electronic devices. This 1D material shows semiconducting properties that can be tuned by modifying its length, width, or topology border; but also, with the presence of defects in form…

Dysprosium-directed metallosupramolecular network on graphene/Ir(111) (CHEM. COMMUN. 2021)

The interest in exploiting the unique properties of lanthanides has led to the recent design of two-dimensional coordination networks incorporating f-block elements on metallic surfaces. In order to take this field to the next step of progression, it is necessary to electronically decouple these two-dimensional architectures from the metallic surface…

From high quality packing to disordered nucleation or phase separation in donor/acceptor interfaces: ClAlPc-C60 on Au(111) (PHYS. CHEM. CHEM. PHYS. 2021)

The dramatic consequences that the orientation adopted by the molecular dipoles, in diverse arrays of chloroaluminum phthalocyanine (ClAlPc) on Au(111), have on the ulterior adsorption and growth of C60 are explored by means of an all scanning probe microscopy approach. The unidirectional downwards organization of the molecular dipoles at the first…

Lanthanide-porphyrin species as Kondo irreversible switches through tip-induced coordination chemistry (NANOSCALE 2021)

Metallosupramolecular chemical protocols are applied to in situ design dysprosium porphyrin complexes on Au(111) by sequential deposition of 2H-4FTPP species and Dy, resulting in the production of premetallated Dy-2H-4FTPP, partially metallated Dy-1H-4FTPP and fully metallated Dy-0H-4FTPP complexes, as determined by scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. A zero…

A Trapezoidal Octacyanoquinoid Acceptor Forms Solution and Surface Products by Antiparallel Shape Fitting with Conformational Dipole Momentum Switch (ANGEW. CHEM. 2021)

A new compound (1) formed by two antiparallelly disposed tetracyano thienoquinoidal units has been synthesized and studied by electrochemistry, UV/Vis-NIR, IR, EPR, and transient spectroscopy. Self-assembly of 1 on a Au(111) surface has been investigated by scanning tunneling microscopy. Experiments have been rationalized by quantum chemical calculations. 1 exhibits a…
