Perhaps the strangest prediction of quantum theory is entanglement, a phenomenon whereby two distant objects become intertwined in a manner that defies both classical physics and a “common-sense” understanding of reality. In 1935, Albert Einstein expressed his concern over this concept, referring to it as “spooky action at a distance”. Nowadays, entanglement is considered [...]
The term ‘DNA origami’ refers to a method for the design and self-assembly of complex molecular structures with nanometer precision. The technique exploits the base-pairing interactions between single-stranded DNA molecules of known sequence to generate intricate three-dimensional nanostructures with predefined shapes in arbitrarily large numbers. The method has great potential for a [...]
Introduction Surface-enhanced Raman spectroscopy (SERS) uses both roughened metal surfaces and nanoparticles in colloidal solutions to enhance the Raman signal. Recent research has also had a focus on zinc oxide nanostructures. Nanoparticles are more commonly used due to the fact they can be easily made in the lab whereas roughened surfaces require complicated lithography [...]
Researchers at The University of Manchester and Shandong University in China have developed a nanoscale transistor that will be one step closer to enabling the creation of flexible televisions, phones, and tablets as well as ‘truly wearable’ smart tech. The international team has created an ultrafast, nanoscale transistor – called a thin film transistor [...]
Recently, applications of nanotechnology are in the lime light in all the sectors including food and nutrition. Food nanotechnology is becoming new frontiers of this century. The applications of nanotechnology in food and agriculture sector are comparatively more recent than the nano-drugs and nanopharmaceuticals. Smart and efficient delivery of active food components, protein bioseparation, [...]
Using chemotherapy along with aptamers – lab-made molecules that function like antibodies — researchers have shown that they can zero in on and kill prostate cancer tumours in mice while leaving healthy tissue unscathed. The finding suggests that aptamers could form the basis of new cancer therapies if additional studies in animals and humans [...]
Frank Boehm (CEO of NanoApps Medical, Inc.) will be interviewed by Dr. Bob Hieronimus , host of 21st Century Radio in Baltimore, Maryland on Sunday, April, 29th from 8-10 pm EST. Dr. Bob and Frank will discuss Frank’s first book on nanomedical device and systems design, as well as the three new books that [...]
One more mutation, and the strain could become untreatable. The first “extensively drug-resistant” strain of typhoid is spreading through Pakistan, leaving scientists concerned about a deadly outbreak and the rise of other drug-resistant diseases. Five different types of antibiotics have proven ineffective against the new strain, which has infected 850 people across Pakistan, according [...]
Our understanding of single-molecule electronics has become clearer and the answer involved using a common household item – salt. Building off of a previous paper in 2009 (Science, "Measuring the Charge State of an Adatom with Noncontact Atomic Force Microscopy"), where IBM scientists and collaborators demonstrated the ability to measure the charge state of [...]
Researchers at the Max Planck Institute for Intelligent Systems together with researchers at the University of Heidelberg and the University of Stuttgart use a technique called DNA origami to mimic a multitude of vital movements seen in nature, such as the sliding motion exerted by protein motors during cell division. Their invention, which is [...]
