“…(18), showing that, apart from size exclusion, there are other factors that strongly affect the diffusion of molecules through nanoporous membranes such as solute-solute and solute-membrane interactions (electrostatic, hydrophobic, charge transfer, or hydrogen bonding interactions). Adiga and coworkers [154] reviewed the basic mechanisms underlying liquid transport in nanoporous membranes with cylindrical nanopores for biomedical applications. In this case, two different expressions were proposed for the effective diffusion coefficient of rigid molecules: Therefore, theoretical models developed for both nanoporous polymeric materials and other nanoporous systems seem to describe the gas storage or fluid transport (both gas and liquid) of solutes through nanoporous membranes accurately.…”

a b s t r a c tNanoporous polymeric materials are porous materials with pore sizes in the nanometer range (i.e., below 200 nm), processed as bulk or film materials, and from a wide set of polymers. Over the last several years, research and development on these novel materials have progressed significantly, because it is believed that the reduction of the pore size to the nanometer range could strongly influence some of the properties of porous polymers, providing unexpected and improved properties compared to conventional porous and microporous polymers and non-porous solids.In this review, the key properties of these nanoporous polymeric materials (mechanical, thermal, dielectric, optical, filtration, sensing, etc.) are analyzed. The experimental and theoretical results obtained up to date related to the structure-property relations are presented. In several sections, in order to present a more compressive approach, the trends obtained for nanoporous polymers are compared to those for metallic and ceramic nanoporous systems. Moreover, some specific characteristics of these materials, such as the consequences of the confinement of both gas and solid phases, are described. Likewise, the main production methods are briefly described. Finally, some of the potential applications of these materials are also discussed in this paper.

Biofouling is generally undesirable for many applications. An overview of the medical, marine and industrial fields susceptible to fouling is presented. Two types of fouling include biofouling from organism colonization and inorganic fouling from non-living particles. Nature offers many solutions to control fouling through various physical and chemical control mechanisms. Examples include low drag, low adhesion, wettability (water repellency and attraction), microtexture, grooming, sloughing, various miscellaneous behaviours and chemical secretions. A survey of nature's flora and fauna was taken in order to discover new antifouling methods that could be mimicked for engineering applications. Antifouling methods currently employed, ranging from coatings to cleaning techniques, are described. New antifouling methods will presumably incorporate a combination of physical and chemical controls.

“…In order to achieve very thin and conformal nanostructured films (necessary for faster sensor response (Tipnis et al 2007)) with precise control of pore size, atomic layer deposition (ALD) technique has also been used. (Adiga et al 2008; Elam et al 2003) ALD techniques employ alternating, self-limiting chemical reactions between gaseous precursor molecules that closely resemble an atomic layer-by-layer assembly process, thereby affording growth of ultrathin membrane structures (Xiong et al 2005). …”

The development of implantable biosensors for continuous monitoring of metabolites is an area of sustained scientific and technological interest. On the other hand, nanotechnology, a discipline which deals with the properties of materials at the nanoscale, is developing as a potent tool to enhance the performance of these biosensors. This article reviews the current state of implantable biosensors, highlighting the synergy between nanotechnology and sensor performance. Emphasis is placed on the electrochemical method of detection in light of its widespread usage and substantial nanotechnology-based improvements in various aspects of electrochemical biosensor performance. Finally, issues regarding toxicity and biocompatibility of nanomaterials, along with future prospects for the application of nanotechnology in implantable biosensors, are discussed.
