Adsorption of synthetic homo- and hetero-oligodeoxynucleotides onto highly oriented pyrolytic graphite: atomic force microscopy characterization.
DNA adsorption on electrode surfaces is of fundamental interest for the development of DNA-based biosensors. The free adsorption of 10-mer synthetic oligodeoxynucleotides (ODNs) onto highly oriented pyrolytic graphite (HOPG) surfaces was studied using Magnetic AC mode atomic force microscopy (MAC Mode AFM). The mechanism of interaction of nucleic acids with carbon electrode surfaces was elucida...
متن کاملElectrogenerated chemiluminescence of partially oxidized highly oriented pyrolytic graphite surfaces and of graphene oxide nanoparticles.
Electrogenerated chemiluminescence (ECL) can be obtained from an electrochemically oxidized highly oriented pyrolytic graphite electrode or a graphene oxide suspension in an aqueous solution containing 0.1 M NaClO(4), phosphate buffer (PBS) (pH = 7.0) and 13 mM tri-n-propylamine. Single ECL events from individual graphene oxide nanosheets can be observed. The observation of ECL in such systems ...
متن کاملUFM observation of lattice defects in highly oriented pyrolytic graphite
Ultrasonic force microscopy (UFM) can be used to image the distribution of elastic modulus up to several tens of GPa, which is not possible by the force modulation mode using a soft cantilever of spring constant less than 1 N m‘. It was shown that by careful design of a piezoelectric transducer, together with a sample with small friction force, deflection vibration of the cantilever without tor...
متن کاملI n Situ Scanning Tunneling Microscopy of the Anodic Oxidation of Highly Oriented Pyrolytic Graphite Surfaces
The scanning tunneling microscope (STM) was used to follow the in situ anodic oxidation of highly oriented pyrolytic graphite (HOPG) in 0.1 M H2S04. Prior to electrochemical cycling, the HOPG surface appeared atomically flat and atomic structure was observed with the surface under potential control. Cycling between 0.0 and 1.8 V vs AgQRE (silver wire quasi-reference electrode) resulted in the f...
متن کاملMesoscopic self-organization of a self-assembled supramolecular rectangle on highly oriented pyrolytic graphite and Au(111) surfaces.
A self-assembled supramolecular metallacyclic rectangle was investigated with scanning tunneling microscopy on highly oriented pyrolytic graphite and Au(111) surfaces. The rectangles spontaneously adsorb on both surfaces and self-organize into well ordered adlayers. On highly oriented pyrolytic graphite, the long edge of the rectangle stands on the surface, forming a 2D molecular network. In co...
