Can Silver Promote the Colonization of Bacteria on Medical Devices? |
| Biomaterials are increasingly being used to replace human organs and tissues. Since biomaterials are susceptible to microbial colonization, silver is often added to reduce the adhesion of bacteria to biomaterials and prevent infections. more info >> |

Fluorescent label sheds light on radioactive contamination |
| Radioactive leaks, such as at the Fukushima Daiichi nuclear plant in Japan, contaminate the local environment. Contamination of soil and water by the radioactive form of caesium is a major problem, since it persists for a long time; levels of radioactivity reduce by half only every 30 years. more info >> |

Gold squeezed into micro-Velcro |
| Velcro consists of one surface with loops, and another with hooks that latch onto the loops, joining opposing surfaces strongly. A miniaturised version of Velcro could be used in micro- and nanotechnology, but to form the surfaces, microwires are needed with properties that provide strength and durability. more info >> |

Hybrid Scaffold More Than Skin Deep |
| Open skin wounds need to be repaired quickly to prevent infection. Using artificial skin substitutes for repair avoids the difficulties of grafts, but an ideal material for a scaffold that's strong and allows regeneration of skin tissue has yet to be found. more info >> |

Microwave Heating Improves Artificial Bone |
| Traditionally, bone grafts require material to be transplanted from either another bone of the patient or from a donor. Artificial grafts offer an easier and less risky process, providing an artificial scaffold on which bone cells can grow. more info >> |
