Designing Artificial Microswimmers for Targeted Drug Delivery

November 24th, 2020 at 9:11 pm » Comments Off

Many types of motile cells, such as the bacteria in our guts, need to propel themselves through confined spaces filled with viscous liquid. Mathematical models of this cell motion are guiding the design of artificial microswimmers for targeted drug delivery. Many types of motile cells, such as the bacteria in our guts and spermatozoa in […]

‘Like having billions of tiny 3D printers’: Scientists train BACTERIA to build complex microscopic structures

November 22nd, 2020 at 4:43 pm » Comments Off

  Researchers at Finland’s Aalto University have successfully turned bacteria into a microscopic workforce of nanobots, using molds made of hydrophobic material to create incredibly intricate three-dimensional objects. The researchers placed the Komagataeibacter medellinensis bacteria in a mould with water and the requisite amount of nutrients like sugar, proteins and air. Once sufficiently fuelled-up, the […]

Researchers create a single-molecule switch

October 31st, 2020 at 10:57 am » Comments Off

  A team of researchers has demonstrated for the first time a single-molecule electret—a device that could be one of the keys to molecular computers.  Smaller electronics are crucial to developing more advanced computers and other devices. This has led to a push in the field toward finding a way to replace silicon chips with […]

Biochip innovation combines AI and nanoparticles to analyze tumors

October 16th, 2020 at 11:25 am » Comments Off

Electrical engineers, computer scientists and biomedical engineers at the University of California, Irvine have created a new lab-on-a-chip that can help study tumor heterogeneity to reduce resistance to cancer therapies. In a paper published today in Advanced Biosystems, the researchers describe how they combined artificial intelligence, microfluidics and nanoparticle inkjet printing in a device that […]

Experimental cancer treatment destroys cancer cells without using any drugs

October 7th, 2020 at 11:33 am » Comments Off

One of the latest methods pioneered by scientists to treat cancer uses a Trojan horse sneak attack to prompt cancer cells to self-destruct – all without using any drugs. Key to the technique is the use of a nanoparticle coated in a specific amino acid called L-phenylalanine, one of several such acids that cancer cells […]

Self-learning robot autonomously moves molecules, setting stage for molecular 3D printing

September 25th, 2020 at 12:34 pm » Comments Off

If you know even just a little bit about science, you probably already know that molecules are often referred to as “the building blocks of life.” Made of a group of atoms that have bonded together, molecules make up all kinds of materials, but behave totally differently in regards to macroscopic objects than atoms do. […]

Scientists create a robot made entirely of living cells

September 8th, 2020 at 11:29 am » Comments Off

A Xenobot, 650-750 microns in diameter. The “legs” help it shuffle around in the petri dish.  ’Xenobots’ could be used to clean up microplastics or deliver medication in the body Scientists have unveiled the first ever “living robot,” an organism made up of living cells, which can move around, carry payloads, and even heal itself. […]

Army of a million microscopic robots created to explore on tiny scale

September 1st, 2020 at 10:07 am » Comments Off

Artist’s rendition of an array of microscopic robots  A troop of a million walking robots could enable scientific exploration at a microscopic level. Researchers have developed microscopic robots before, but they weren’t able to move by themselves, says Marc Miskin at the University of Pennsylvania. That is partly because of a lack of micrometre-scale actuators […]

Atom-by-atom assembly makes for cheap, tuneable graphene nanoribbons

July 10th, 2020 at 3:54 am » Comments Off

Graphene nanoribbons could serve a variety of purposes, and a new way to produce then could help unleash this potential The wonder material graphene can take many forms for many different purposes, from transparent films that repel mosquitoes to crumpled balls that could boost the safety of batteries. One that has scientists particularly excited is […]

New graphene battery recharges blazingly fast, and it’s already on the market

January 19th, 2020 at 8:54 pm » Comments Off

Faster charging, longer lasting, and lower temperatures. These are the three major benefits from a lithium battery that has been infused with wonder-material graphene. Thing is, we’ve all heard about the benefits of graphene before, but despite all the hype, we’ve yet to really see it used in devices and products that you can actually […]

Researchers demonstrate chip-to-chip quantum teleportation

December 29th, 2019 at 12:09 am » Comments Off

Llewellyn et al realize an array of microring resonators (MRRs) to generate multiple high-quality single photons, which are monolithically integrated with linear-optic circuits that process multiple qubits with high fidelity and low noise. A research team led by University of Bristol scientists has successfully demonstrated quantum teleportation of information between two programmable micrometer-scale silicon chips. […]

A nanotube material conducts heat in just one direction

December 21st, 2019 at 2:49 am » Comments Off

Photograph of nanotubes being created  Asymmetric conductors could revolutionize cooling systems for computers and other devices. Heat is something of a nuisance for electrical engineers. It reduces the reliability of electronic devices and even causes them to fail completely. That’s why computer components are liberally smeared with thermal paste and connected to heat pipes, fans, […]
