Going swimmingly: Biotemplates breakthrough paves way for cheaper nanobots

Added: 14.12.2017 3:30 | 0 views | 0 comments

New developments may now propel nanoswimmers from science fiction to reality thanks to unexpected help from bacteria. Engineers have demonstrated a new technique for plating silica onto flagella, the helix-shaped tails found on many bacteria, to produce nanoscale swimming robots. The group's biotemplated nanoswimmers spin their flagella thanks to rotating magnetic fields and can perform nearly as well as living bacteria.

Just imagine, you are sitting on a sunny beach, contentedly letting the warm sand trickle through your fingers. Millions of sand grains. What you probably can't imagine: at the same time, billions upon billions of bacteria are also trickling through your fingers. Between 10,000 and 100,000 microorganisms live on each single grain of sand, as revealed in a new study. This means that an individual grain of sand can have twice as many residents as, say, the city of Fairbanks, Alaska!

Lactic acid bacteria, commonly used as probiotics to improve digestive health, can offer protection against different subtypes of influenza A virus, resulting in reduced weight loss after virus infection and lower amounts of virus replication in the lungs, according to a new study.

Nanotexturing creates bacteria-killing spikes on stainless steel surfaces

Added: 13.12.2017 17:59 | 1 views | 0 comments

By using an electrochemical etching process on a common stainless steel alloy, researchers have created a nanotextured surface that kills bacteria while not harming mammalian cells. If additional research supports early test results, the process might be used to attack microbial contamination on implantable medical devices and on food processing equipment made with the metal.
