“…As shown in Fig. 20, if we can assure extra-clean solutions and solve the problems associated with the molecular assembly and electrode contact, then by utilizing a combination of techniques [96,97,98,99], we may develop nanoparticlecoupled multiple molecular junctions in a single nanowire. If this design can be experimentally realized, it might be an important step toward the generation of bio-molecule-nanostructure hybrid nanostorage systems.…”

The object of this article is to review the development of ultrahigh-density, nanoscale data storage, i.e., "nanostorage". As a fundamentally new type of storage system, the recording mechanisms of nanostorage may be completely different to those of the traditional devices. Currently, two types of 'molecules' are being studied for potential application in nanostorage. One is molecular electronic elements including molecular wires, rectifiers, switches, and transistors. The other approach employs nanostructured materials such as nanotubes, nanowires, and nanoparticles. The challenges for nanostorage are not only the materials, ultrahigh data-densities, fabrication-costs, device operating temperatures and large-scale integration, but also the development of the physical principles and models. There are already some breakthroughs obtained, but it is still unclear what kind of nanostorage systems can ultimately replace the current silicon based transistors. A promising candidate may be a molecular-nanostructure hybrid device with sub-5 nm dimensions.

“…7 Contact angle measurement has been proved to be an efficient way in detecting the interfacial properties including the characterization of the hydrophilic/hydrophobic features, wetting properties of monolayer and thin film-functionalized surfaces. [8][9][10] In this study, we have explored a new combination between contact angle and electrochemical detection. This in-situ technique was utilized to simultaneously control and detect the variation of interfacial properties as well as electrochemical responding.…”

Dendrofullerene (C 60 DF) is a novel fullerene derivative with potential and promising biomedical applications. In this work, electrochemical/contact angle behavior of C 60 DF in the cellular system has been explored by in-situ electrochemical contact angle measurement. This measuring system is a newly developed technique which can provide electrochemical and contact angle detection simultaneously. The electrochemical results indicate that dendrofullerene may effectively bind and permeate the tumor cell membrane and then distribute into the cancer cells. Our observations of in-situ electrochemical contact angle measurement also illustrate that the permeation and interaction of C 60 DF with target cancer cells may lead to some variation of the configurational structure of the relative cell membrane and thus result in the change of hydrophilic/hydrophobic properties of target cellular system. Furthermore, through confocus fluorescence microscopy study we found that, upon application of C 60 DF, the intracellular accumulation of anticancer drug daunorubicin in leukemia K562 cells could be remarkably enhanced by C 60 DF. Therefore fullerene derivatives were demonstrated to be a good candidate that can play an important role in improving the intracellular drug uptake in the target cancer cells.
