Bacterial Hair Conducts Electricity and Could Be Used in Bioelectronic Devices

Scientists from the University of Massachusetts at Amherst, Holy Cross, and Brookhaven National Laboratory have discovered that the filaments present in the surface of Geobacter bacteria have conductive properties comparable to those of copper. The finding, published in the journal mBio, could accelerate the introduction of biological material in nanoscale electronical devices. In general, proteins are […]

Nanothermomether Built with DNA

Illustration: istockphotos   Researchers from the University of Montreal have designed a DNA thermometer 20000 times smaller than a human hair. The scientists took advantage of DNA’s natural changes in compaction when subject to temperature variations. The DNA thermometer, which measures temperature at the nanoscale, serves as a proof of concept for building new nanodevices. […]

A More Precise Nanopore Sequencer Based on Polymer-Tagged Nucleotides

Researchers from Columbia University School of Engineering and Applied Science have developed an advanced real-time, single-molecule nanopore sequencer. In collaboration with Genia Technologies (Roche), Harvard University and the National Institute of Standards and Technology (NIST), the engineers built an electronic DNA sequencer with better resolution than current nanopore devices. The study was published in the journal PNAS. Genome sequencing has allowed […]

A Hybrid Polymer With Removable Compartments

A new kind of hybrid polymer could be used for self-repairing materials, drug delivery and artificial muscles. The polymer, developed by researchers at Northwestern University, features removable parts that can be regenerated. The study has been published in the journal Science. Our bodies use polymers to sustain cellular structures. For example, the cytoskeleton is made of fibers […]

Ultra-Thin Pressure Sensor Could Be Used to Detect Breast Cancer

A team of scientists from Japan and the US led by the University of Tokyo have developed an ultra-thin pressure sensor that could be used to detect breast cancer. The sensor maintains its accuracy in calculating pressure distribution when deformed to adapt to curved surfaces. The study has been published in the journal Nature Nanotechnology. […]

Dendrimer Nanoparticles Successfully Deliver RNA Drug to Cancerous Liver

Researchers from the University of Texas Southwestern (UTSW) Medical Center have successfully delivered small-RNA drugs to a cancerous liver by introducing them in synthetic nanoparticles. The dendrimers didn’t damage the healthy tissues near the carcinoma. The study has been published in the journal Proceedings of the Natural Academy of Sciences. Liver cancer is the second leading cause […]

Nanopore Diagnostics Raises $600000 to Develop the iNDxer

American startup Nanopore Diagnostics has raised $600000 to develop The iNDxer, a device to detect bacterial infections. The money, provided by the Missouri Technology Corporation and other minor investors, will be allocated to conduct clinical trials that will validate the use of the Nanopore Diagnostics’ device by physicians. Nanopore Diagnostics CEO Tom Cohen was mistakenly […]

Faster Nanopore Sequencing Simulation Based on Graphene Nanoribbons

Nanopore sequencing technology could be faster and more accurate, according to a simulation by the National Institute of Standards and Technology (NIST). In the recently developed model, DNA passes through a nanohole in the middle of an ultra-thin graphene sheet functionalized with nitrogenous bases that retain its complementary DNA nucleotide, generating a specific electrical signal. The study was published in the […]
