“…The potential use of DNA as an element in various electronic devices promotes the study of the physicochemical properties of interfaces between DNA, inorganic semiconductors, and metal substrates and structures. , As the fabrication and functioning of many of the potential interfaces are in ultrahigh vacuum (UHV), the synthesis and study of the chemistry of such systems in vacuo are of great interest as well. − It should be noted that the chemical nature of the DNA–metal interfaces created in UHV may strongly differ from that of DNA–metal complexes in solution, as was found, for example, for a protein–metal interface created in vacuo …”

The rapidly developing field of bionanotechnology requires detailed knowledge of the mechanisms of interaction between inorganic matter and biomolecules. Under conditions different from those in an aqueous solution, however, the chemistry of these systems is elusive and may differ dramatically from their interactions in vitro and in vivo. Here, we report for the first time a photoemission study of a metal silver-DNA interface, formed in vacuo, in comparison with DNA-Ag and fluorescent DNA-Ag complexes formed in solution. The high-resolution photoelectron spectra reveal that in vacuo silver atoms interact mainly with oxygen atoms of the phosphodiester bond and deoxyribose in DNA, in contrast to the behavior of silver ions, which interact preferentially with the nitrogen atoms of the bases. This offers new insight into the mechanism of DNA metallization, which is of importance in creating metal-bio interfaces for nanotechnology applications.

“…[115][116][117][118][119] However, alternative bottom-up methodologies using molecular self-assembly 120,121 or self-assembled templates [122][123][124][125] do not require specialised instrumentation and are therefore cheaper and potentially faster. For the use of self-assembled planar S-layer templates, methods for inorganic nanostructuring range from the deposition of metal or metal oxide films onto the lattice sheets followed by selective removal using ion milling, [126][127][128][129] over the growth of quantum dots within S-layer pores, 130 to the synthesis of metal particles via chemical, [131][132][133] electrochemical, 134 or electron beam-induced reduction. 132,135,136 Rather than synthesising nanoparticles on S-layer substrates, preformed inorganic and metal nanoparticles can also be deposited directly onto the regular protein sheets.…”

Many biologically relevant structures are formed by the self-assembly of identical protein units. Examples include virus capsids or cytoskeleton components. Synthetic biology can harness these bottom-up assemblies and expand their scope for applications in cell biology and biomedicine. Nanobiotechnology and materials science also stand to gain from assemblies with unique nanoscale periodicity. In these disciplines, the soft scaffolds can serve as templates to produce new metallic or inorganic materials of predefined dimensions. This review article describes how the structure and function of biological assemblies has inspired researchers to develop engineered systems with designed properties for new biomolecular applications.

The use of masks coming from research field as different as colloids, polymers or nanomaterials is a recently emerging field. Recent advances in this area have developed a variety of practical routes which have a great potential to overcome or at least complete the high-cost lithographic techniques. This review focuses on three techniques that try to reduce to the nanometer range, the size of the mask. The major difference between these procedures is related to the type of mask used. The first technique is called colloidal lithography, the mask is a monodispersed-beads template. The second is the block copolymer lithography and the third technique is the nanocrystal lithography, the mask used is a nano-object. For these three parts, the synthetic routes, the improvements and the applications as well as the limitations will be presented.
