Bistable rotaxanes might be pressed into service as valves so that nanoparticles only release drugs in desired target areas.
In yet another approach to using scanning probe microscopy to build better computer memories, nanotech draws and erases lines three nm wide.
We’ve been critical in the past of Saudi Arabia’s policy of having women researchers in nanotechnology (and of course other fields as well) work separately from male researchers. Now King Abdullah has moved personally to fund, at the US$10 billion level, a new graduate-level university with a new policy toward women, to be advised by… Continue reading Saudis to permit co-ed nanotechnology
A new theoretical framework for nanotech seeks to use specially designed nanoparticles to create circuits that could lead to optical information processing and optical communication between nanostructures.
We’ve written here before about the plan to put iron nanoparticles in the ocean as a way to increase growth of plankton, thereby absorbing carbon dioxide. Previously this was to be done by a company called Planktos; now a new company called Climos is making similar plans. There was controversy about Planktos, and no doubt… Continue reading Ocean iron fuss is not about nanotechnology
As a follow-up to Monday’s post on optimizing nanoparticle design for nanotech drug delivery, the same research group has also demonstrated the advantages of a multistage approach in which micrometer-sized mesoporous particles are used to deliver two different nanoparticles in a way that circumvents some of the biological barriers that bedevil attempts to precisely deliver… Continue reading Nanotechnology uses two-stage vehicle to deliver drugs
Proponents of replacing gasoline with hydrogen for fueling cars have to find a practical way to store hydrogen. One potential nanotech-based solution is presented by the recent demonstration that hydrogen can form chemical bonds with most of the carbon atoms in single-walled carbon nanotubes of the appropriate diameter (2.0 nm). From “The March of the… Continue reading Nanotechnology may provide a practical way to store hydrogen
It’s just a concept for now, but Nokia is projecting a future phone product that uses nanotechnology to be stretchable and flexible: Finnish handset giant Nokia gave the industry a glimpse of the future on Monday, when it unveiled a shape changing mobile devices concept based on nanotechnology… The concept demonstrates how future mobile devices… Continue reading Shape-changing nanotechnology phone
Nanotechnology catalysts may enable more efficient fuel cells to power consumer electronics via the oxidation of methanol.
Nanotech drug delivery vehicles may soon improve because it turns out that even those that appear to be promising are not well-designed.
