Attaching biomolecules to carbon nanotubes

Among the many potential biology-related applications proposed for carbon nanotubes (CNTs) are high-sensitivity biosensors and bio-fuel cells. In order to create the synergy between the biomolecules and CNTs required to realize these applications, biomolecules, such as proteins and DNAs, must be connected to the CNTs.

Smart magnetic hydrogels for drug release

Smart magnetic hydrogels were investigated by researchers in Taiwan for the development of a new magnetically induced drug delivery system. By applying magnetic fields, they were able to switch the the drug release profile of the hydrogels between on and off mode.

Controlled drug delivery systems in neurodegenerative diseases

It still is a huge challenge to treat neurodegenerative diseases such as Alzheimer, Parkinson or Huntington, which are increasingly affecting our society as the average life-span of our population increases. One of the main obstacles for successful therapy of these disorders is safe and effective drug delivery to the central nervous system.

High-pressure nano-structuring of materials

Tightly focused femtosecond laser pulses have been used to modify transparent dielectric materials, to form voids, and to polymerize resists and resins for more than a decade. A high sub-100-nm spatial resolution has now been reached making it potentially a nano-fabrication tool.

Lithographically defined self-assembled nanoparticle films

Researchers at the University of New Mexico have demonstrated a new, simple, and facile approach to the fabrication of various nanopatterned films composed of nanoparticles. The findings could lead to nanoparticle sensors for both biological and chemical species.

New nano-contouring measurement techniques

Contouring measurement methods are important for high quality, high speed and productivity machining in order to achieve the high precision required. Among the most commonly used methods, no measuring techniques have been available with nanometer resolution except for the grating encoder measurement system.
