Molecular Robots to Build Drug Molecules

Scientists in the UK have developed a microscopic molecular machine that can be used to assemble individual molecules. The technology could allow scientists to build drug molecules from scratch, as well as help with drug discovery. The molecular robots are only a millionth of a millimeter in size and each has a tiny robotic arm. […]

Acoustofluidics Pulls Exosomes from Whole Blood

Exosomes are tiny vesicles that are released by the body’s myriad of cells and that are found in blood, urine, and other bodily fluids. Their role within our bodies is still largely a mystery, but there’s already considerable evidence that they may be biomarkers of disease and indicators that certain processes are happening within the [ (Read more...)

Microneedle Patch Burns Fat Below Skin

Researchers in the US have developed a microneedle patch that can be applied to the skin and help to burn fat locally. The patch releases a drug that converts white fat to energy-burning brown fat, and could help to reduce “love handles”, and treat obesity and diabetes. Medgadget recently covered drug-loaded nanoparticles that (Read more...)

New Way to Deliver Chemo Agent Helps Reach Brain Tumors

While there are fairly effective medications that can kill brain tumors, getting them to their targets is so challenging that they’re often next to useless for cancers of the brain. Japanese scientists from Kawasaki Institute of Industrial Promotion, The University of Tokyo, and Tokyo Institute of Technology have developed a shell for epirubi (Read more...)

Quantum Dots Light Up Tumors Brighter Than Ever Before

Scientists at the Sanford Burnham Prebys Medical Discovery Institute (SBP) in San Diego, California have devised a way to optically image tumors with unprecedented clarity using quantum dots. These nano structures are tiny particles, only a few nanometers wide, that generate light of a specific wavelength when they’re themselves stimulated by (Read more...)

Nanocages Made of DNA Strands Release Small Molecules to Improve Challenging Studies Inside Body

Many of the activities happening within our bodies are incredibly difficult to study, as some happen in hard to reach places and their timespan is very short. The action of neurosteroids, chemicals that perform an important role in the lives of neurons, is one such topic. Neurosteroids take less than a second to act, and getting anywhere (Read more...)

Nanoparticles to Deliver mRNA: Just Add Water

Scientists at the Fred Hutchinson Cancer Research Center in Seattle, Washington have developed a nanoparticle messenger RNA (mRNA) delivery system to temporarily change gene expression in treated cells. Growing specific cell types in a lab and then administering them to patients is the goal of cell therapies, and these types of treatments are comin (Read more...)

Nanomachines to Drill Through Cell Membranes

An international team of scientists has developed tiny motorized molecules that can drill holes in cells membranes when stimulated by light. The nanomachines could be useful for drug delivery or directly killing cancer cells. The nanomotors are paddle-like chains of atoms, which spin up to 2–3 million times a second when supplied with energy (Read more...)

Flexible Skin Worn Electricity Generator Powered by Sweat

Engineers at the University of California, San Diego have developed what they claim is by far the most powerful wearable fuel cells that run on sweat and produce enough electricity to energize small components such as LEDs and Bluetooth radios. The stretchable devices stick to the skin and conform to its movements, maintaining the ability to [ (Read more...)

Ultrasound and Microbubbles for Targeted Chemotherapy Delivery

Researchers in Norway have developed a chemotherapy delivery system consisting of microbubbles containing drug-loaded nanoparticles. When the researchers apply ultrasound to the microbubbles in a tumor, the microbubbles burst, releasing the nanoparticles and the chemotherapeutic drug. Researchers worldwide are trying to develop new ways to increase (Read more...)

Silver Nanoparticle Coating and Tiny Electric Current Prevent Bacteria from Settling on Medical Devices

Silver ions and electric current are well known killers of bacteria that have been utilized to keep things clean in different scenarios for many years. Yet, their use is limited to only certain applications as a fairly high current or potentially toxic concentration of silver ions are needed to destroy bacterial buildup. At the Karolinska (Read more...)

Paper Test for Zika Powered by Gold Nanoparticles

Zika is often a silent disease that might not display any symptoms in infected persons, making screening particularly important. In the developing world, mobile testing systems that can be easily transported and used are not available, so sending a sample to a lab is still required to detect Zika infected individuals. Researchers at Washington Univ (Read more...)
