Mixing two types of nanoparticle triggers structure change

Last month we reported research aimed at improving targeted drug delivery to specific types of cells by endowing nanorobots with the ability to compute. A recent report indicates it might be possible to achieve a subset of those goals—improving drug delivery by only having drug release happen inside cells that satisfy two target conditions—simply by mixing nanoparticles composed of polymers with opposite steric configurations. …

Penta-graphene a new form of carbon for chemistry and nanotechnology

If nanotechnologists were to vote on their favorite atom, the winner would, I would guess, be carbon. Not only do diamond-like structures figure prominently in theoretical proposals for high throughput atomically precise manufacturing, not only does carbon bind in a wondrous variety of ways with itself and other atoms to form the molecules that underlie life and present day biomimetic nanotechnology, but a variety of allotropes of carbon exhibit a range of interesting properties that make possible a number of current day nanotechnologies. Now graphite, diamond, fullerenes, graphene, carbon nanotubes, glassy carbon, and carbon nanofoam are joined by another allotrope—penta-graphene. …

Adding layer to a piezoelectric nanostructure increases output voltage

Sometimes very simple modifications of nanoscale structure can have large practical implications. Last month we noted the unexpected discovery of piezoelectricity in a molecular monolayer. The research noted today achieved a large increase in voltage output of a nanostructure several hundred nanometers thick (a vertically integrated nanogenerator, or VING) through the insertion of an insulating layer. …

Simple nanotechnology modification of alumina surface discourages bacteria

Current nanotechnology research spans the range from steps toward molecular machine systems and nanorobots to simple nanoscale materials modifications that can have immediate and substantial practical value, such as this example that changes the electrical charge and surface energy of a metal surface. …

A tunable hinge joint for DNA nanotechnology

Our most recent post cited research that demonstrated programmed complex motions in simple mechanisms fabricated using scaffolded DNA origami. This achievement represents initial success in what appears to be a systematic program to implement macroscale engineering design principles in molecular machinery made possible by structural DNA Nanotechnology. This approach was introduced in a 2013 paper published in ACS Nano implementing a collaboration between a DNA nanotechnology research group and a mechanical engineering and kinematics design innovation and simulation research group. …

Structural DNA nanotechnology with programmed motions

Progress in structural DNA nanotechnology seems to be accelerating. For example, a few weeks ago we cited work in which swarms of DNA nanorobots executed complex tasks in living animals. For the most part, this progress has centered on static structures, or on structures embodying small movements along loosely constrained paths. Now a team of researchers is beginning to use DNA nanotechnology to fabricate parts for machine designs based on the way macroscopic machines work by implementing well-defined motions. …

About the Foresight Institute
Foreseeing Future Technologies

Advancements in technologies such as nanotech, robotics, and biotech are promising to make major differences in our lives in the not-too-distant future, as the Industrial Revolution did to the agrarian world — to do for the physical world what the computer and Internet have done to the world of information.

Since 1986, the Foresight Institute has been in the forefront of a worldwide community of visionaries who work to help shape these possibilities into a positive, beneficial reality.

If you would like to help us understand the potential of these technologies, and influence their direction, please consider becoming a member of the Foresight community. With your support, Foresight will continue to educate the general public on these technologies and what they will mean to our society.

The Foresight Institute is a non-profit, member-supported 501(c)(3) organization. We offer membership levels appropriate to meet the needs and interests of individuals and companies. Donations are tax deductible.
