A polysaccharide bioprotonic field-effect transistor

Abstract In nature, electrical signalling occurs with ions and protons, rather than electrons. Artificial devices that can control and monitor ionic and protonic currents are thus an ideal means for interfacing with biological systems. Here we report the first demonstration of a biopolymer protonic field-effect transistor with proton-transparent PdHx contacts. In maleic-chitosan nanofibres, the flow [...]

Biomolecule imprinting: Developments in mimicking dynamic natural recognition systems

Abstract The principle of molecular imprinting has repeatedly been proven a successful and effective means of creating sites of specific recognition within polymers. After almost three decades of development, we finally have some evidence of large molecule imprinting…We describe here some of the new and innovative work that endeavours to take molecular imprinting away from [...]

Biomimetic strategies based on viruses and bacteria for the development of immune evasive biomaterials

Abstract The field of biomaterials has begun to focus upon materials strategies for modulating the immune response. While certain approaches appear promising, they are currently limited to isolated facets of inflammation process. It is well documented that both bacteria and viruses have highly developed methods for evading the immune system, providing inspiration for a more [...]

Micro- and nanotechnologies for intelligent and responsive biomaterial-based medical systems

Abstract …Combination of micro- and nano-fabricated systems with intelligent biomaterials that have the ability to sense and respond is a promising avenue for the development of better diagnostic and therapeutic medical systems. Micro- and nano-electromechanical systems (MEMs and NEMs) are now becoming a family of potentially powerful new technologies for drug delivery, diagnostic tools, and [...]

Anti-fouling bioactive surfaces

Abstract Bioactive surfaces refer to surfaces with immobilized bioactive molecules aimed specifically at promoting or supporting particular interactions. Such surfaces are of great importance for various biomedical and biomaterials applications. In the past, considerable effort has been made to create bioactive surfaces by forming specific biomolecule-modified surfaces on a non-biofouling “base” or “background”. Hydrophilic and [...]
