TL;DR: This review focuses on some of the nano-sized systems used in drug delivery and discusses the potential applications of nanotechnology in the delivery of macromolecular therapeutic agents.
Abstract: Nanotechnology is a novel branch of science that deals with the characterization, creation, and utilization of materials, devices, and systems at the nanometer scale. Advances in nanotechnology are spurring a revolution in science, engineering and therapeutics, particularly in drug delivery. Targeted delivery of therapeutic molecules is the most desirable feature of an effective drug therapy. Conventional chemotherapy faces major drawbacks such as poor specificity of the drug, increased adverse effects, and reduced therapeutic efficacy. Application of nanotechnology in drug delivery systems has provided new avenues for engineering materials with molecular precision. This aids in fabricating nanoscale delivery devices that combine diagnostic and therapeutic actions for immediate administration of therapy. Nanotechnology can generate a library of sophisticated drug delivery systems that integrate molecular recognition and site-specific delivery of the therapeutic agents. It formulates therapeutic agents in biocompatible nanomaterials such as nanoparticles, nanocapsules, liposomes, and micelles. This review focuses on some of the nano-sized systems used in drug delivery and discusses the potential applications of nanotechnology in the delivery of macromolecular therapeutic agents.

TL;DR: This Chapter examines the biological applications of various soft lithographic techniques, with particular attention to the main general features of soft lithography and of materials commonly employed with these methods.
Abstract: An entirely new scientific and technological area has been born from the combination of nanotechnology and biology: nanobiotechnology. Such a field is primed especially by the strong potential synergy enabled by the integration of technologies, protocols, and investigation methods, since, while biomolecules represent functional nanosystems interesting for nanotechnology, micro- and nano-devices can be very useful instruments for studying biological materials. In particular, the research of new approaches for manipulating matter and fabricating structures with micrometre- and sub-micrometre resolution has determined the development of soft lithography, a new set of non-photolithographic patterning techniques applied to the realization of selective proteins and cells attachment, microfluidic circuits for protein and DNA chips, and 3D scaffolds for tissue engineering. Today, soft lithographies have become an asset of nanobiotechnology. This Chapter examines the biological applications of various soft lithographic techniques, with particular attention to the main general features of soft lithography and of materials commonly employed with these methods. We present approaches particularly suitable for biological materials, such as microcontact printing (μCP) and microfluidic lithography, and some key micro- and nanobiotechnology applications, such as the patterning of protein and DNA microarrays and the realization of microfluidic-based analytical devices.

TL;DR: This review presents some possibilities and strategies to efficiently delivery peptides, proteins, gene and RNA interference using nanotechnology approach.
Abstract: Biotechnology and nanotechnology are fields of science that can be applied together to solve a variety of biological issues. In the case of human health, biotechnology attempts to improve advances on the therapy against several diseases. Therapeutic peptides and proteins are promissory molecules for developing new medicines. Gene transfection and RNA interference have been considered important approaches for modern therapy to treat cancer and viral infections. However, because of their instability, these molecules alone cannot be used for in vivo application, since they are easily degraded or presenting a poor efficiency. Nanotechnology can contribute by the development of nanostructured delivery systems to increase the stability and potency of these molecules. Studies involving polymeric and magnetic nanoparticles, dendrimers, and carbon nanotubes have demonstrated a possibility to use these systems as vectors instead of the conventional viral ones, which present adverse effects, such as recombination and immunogenicity. This review presents some possibilities and strategies to efficiently delivery peptides, proteins, gene and RNA interference using nanotechnology approach.

TL;DR: It is shown that chemical and topographical patterns can be obtained on different substrates, with dimensions down to a few tenths of 10 nm, and the applications of these nanostructured surfaces in biology, biochemistry and biodetection are presented.
Abstract: We present an overview of the possibilities offered by plasma technologies, in particular the combination plasma polymers deposition, colloidal lithography, e-beam lithography and microcontact printing, to produce micro- and nanostructured surfaces with chemical and topographical contrast for applications in nanobiotechnology. It is shown that chemical and topographical patterns can be obtained on different substrates, with dimensions down to a few tenths of 10 nm. The applications of these nanostructured surfaces in biology, biochemistry and biodetection are presented and the advantages and limitation of the plasma techniques in this context underlined.
