A minuscule part of the body possessing immense power, the intracellular forces inside our cells have been shown to control cell function, and by extension, the body’s systems. The physical … Continue Reading Nanodevices can be injected into live cells to track internal changes.
Antibiotics are medicines used to prevent and treat bacterial infections. Antibiotic resistance occurs when bacteria adapt in response to the use of these medicines and become immune to their mode … Continue Reading Deadly superbugs killed by molecular drills.
With the rapid advancement of robotic research, it has become increasingly important to develop biomimetic micro- or nanorobots capable of translating biological principles into robotic systems. Now, a study from … Continue Reading Biomimetic nanobots clear bacteria and toxins from blood.
Robots are an important type of molecular machine capable of automatically carrying out complex nanomechanical tasks. DNA molecules are excellent materials for building molecular robots as their geometric, thermodynamic, and … Continue Reading First autonomous cargo-sorting DNA nanobot developed.
Semen quality is a measure of the ability of semen to accomplish fertilization and a measure of fertility in a man. It is the sperm in the semen that are … Continue Reading ‘Spermbots’ successful in proof-of-concept fertility studies.
Expanded use of engineered nanoparticles in consumer products and drug delivery increases the potential for environmental release, overexposure or unintended biological exposure. As a result, extraction techniques with integrated measurement … Continue Reading New technique can remove nanoparticles unaltered from blood with ease.
Cellular therapy for traumatic brain injury (TBI) has been suggested to replace cellular loss, restore growth factors homeostasis, repair damaged circuits and improve functional recovery. Stem cell therapy for TBI … Continue Reading Nano-magnetic cell targeting used to treat TBI in animal model.
Over the past three decades DNA has emerged as an exceptional molecular building block for nanoconstruction due to its predictable conformation and programmable base-pairing interactions. DNA nanotechnology is the design … Continue Reading Low-cost DNA nanobot can detect many diseases, including HIV.
Seeking to advance minimally invasive medical treatments, researchers from University of Houston and Harvard Medical School have proposed using millibots, driven by magnetic potential energy from magnetic resonance imaging (MRI) … Continue Reading Medical millibots for less-invasive surgeries moving out of proof-of-concept studies.
Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, state researchers from the University of Montreal, Polytechnique Montréal and CHU Sainte-Justine. This barrier runs inside almost … Continue Reading Radio-controlled nanobots open the blood-brain barrier just the right amount in murine studies.
Nanometer-sized drones that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis, if an animal … Continue Reading Nanobot ‘drones’ successfully target atherosclerosis in animal model.
Researchers at the University of California have shown that a micromotor fueled by stomach acid can take a bubble-powered ride inside a mouse. These tiny motors, each about one-fifth the … Continue Reading Stomach acid-powered nanobots get their first test in a living animal.
