Anti-cancer therapy delivering drug to an entire tumor developed

Posted on by

Researchers in South Korea have developed a new highly efficacious anti-cancer nanotechnology by delivering anti-cancer drugs uniformly to an entire tumor.

Korea Advanced Institute of Science and Technology (KAIST)'s Department of Bio and Brain Engineering Professor Ji-Ho Park and his team successfully developed a new highly efficacious anti-cancer nanotechnology by delivering anti-cancer drugs uniformly to an entire tumor. Their research results were published in Nano Letters online on March 31, 2015.

To treat inoperable tumors, anti-cancer medicine is commonly used. However, efficient drug delivery to tumor cells is often difficult, treating an entire tumor with drugs even more so.

Using the existing drug delivery systems, including nanotechnology, a drug can be delivered only to tumor cells near blood vessels, leaving cells at the heart of a tumor intact. Since most drugs are injected into the bloodstream, tumor recurrence post medication is frequent.

Therefore, the team used liposomes that can fuse to the cell membrane and enter the cell. Once inside liposomes the drug can travel into the bloodstream, enter tumor cells near blood vessels, where they are loaded to exosomes, which are naturally occurring nanoparticles in the body. Since exosomes can travel between cells, the drug can be delivered efficiently into inner cells of the tumor.

Exosomes, which are secreted by cells that exist in the tumor microenvironment, is known to have an important role in tumor progression and metastasis since they transfer biological materials between cells. The research team started the investigation recognizing the possibility of delivering the anti-cancer drug to the entire tumor using exosomes.

The team injected the light-sensitive anti-cancer drug using their new delivery technique into experimental mice. The researchers applied light to the tumor site to activate the anti-cancer treatment and analyzed a tissue sample. They observed the effects of the anti-cancer drug in the entire tumor tissue.

The team's results establish a ground-breaking foothold in drug delivery technology development that can be tailored to specific diseases by understanding its microenvironment. The work paves the way to more effective drug delivery systems for many chronic diseases, including cancer tumors that were difficult to treat due to the inability to penetrate deep into the tissue.

The team is currently conducting experiments with other anti-cancer drugs, which are being developed by pharmaceutical companies, using their tumor-penetrating drug delivery nanotechnology, to identify its effects on malignant tumors, which were difficult to penetrate with existing technology.

Professor Park said, "This research is the first to apply biological nanoparticles, exosomes that are continuously secreted and can transfer materials to neighboring cells, to deliver drugs directly to the heart of tumor."

Wearable Electronics' Newest Wrinkle: Power-Producing Cloth

Posted on by

Good-bye charging cords and batteries. Wearable electronics such as the Apple Watch might soon power themselves with a clean, portable energy source: human motion.

If cutting-edge nano science pans out, limited battery life may no longer be the bugaboo of everyday technology. At universities worldwide, researchers are finding new ways to produce power from walking, typing, and other basic activities.

Their progress, documented in at least 146 scientific papers in the last three years, holds promise not only for wearable devices but also for keyboards, smartphones, laptops, and biomedical applications such as robotic skins.

"Self-powered electronics will play a critical role in the Internet of Things," in which people and devices are seamlessly connected, says Zhong Lin Wang, a leading researcher in nanotechnology as regents' professor of engineering at Georgia Institute of Technology. (Read about how scientists also develop nanobatteries.)

The basic principlestatic electricityis ancient. It focuses on the friction that occurs when two dissimilar materials touch each other. It's basically the spark that can occur when combing your hair, putting on a freshly laundered fleece in winter, or touching a doorknob after shuffling across carpet.

What's new are the minuscule materials, typically a fraction of the width of human hair. The result: Nanogenerators that are triboelectric, which stems from the Greek word for "rub."

A new backpack device harnesses the energy created by people walking to light more than 40 commercial LEDs.

The latest example is a flexible and foldable cloth that, in lab experiments, powered LEDs, a liquid crystal display, and a vehicle's keyless-entry remote. Here's how it worked: A team of Korean and Australian researchers stacked together four pieces of this clothcoated with nanorods and a silicon-based organic materialand then pushed down on the material and captured the energy generated from that pressure.

"The cloth worked for more than 12,000 cycles, showing very good mechanical durability," says Sang-Woo Kim of Korea's Sungkyunkwan University, lead author of a paper that was published last month in the peer-reviewed journal ACS Nano.

"Cost is not a big hurdle for commercialization," he says, noting the materials are inexpensive. Yet the smart cloth needs to be washable, so his team is pursuing "novel technology" to make it waterproof.

Optics, nanotechnology combined to create low-cost sensor for gases

Posted on by

Engineers have combined innovative optical technology with nanocomposite thin-films to create a new type of sensor that is inexpensive, fast, highly sensitive and able to detect and analyze a wide range of gases.

The technology might find applications in everything from environmental monitoring to airport security or testing blood alcohol levels. The sensor is particularly suited to detecting carbon dioxide, and may be useful in industrial applications or systems designed to store carbon dioxide underground, as one approach to greenhouse gas reduction.

Oregon State University has filed for a patent on the invention, developed in collaboration with scientists at the National Energy Technology Lab or the U.S. Department of Energy, and with support from that agency. The findings were just reported in the Journal of Materials Chemistry C.

University researchers are now seeking industrial collaborators to further perfect and help commercialize the system.

"Optical sensing is very effective in sensing and identifying trace-level gases, but often uses large laboratory devices that are terribly expensive and can't be transported into the field," said Alan Wang, a photonics expert and an assistant professor in the OSU School of Electrical Engineering and Computer Science.

"By contrast, we use optical approaches that can be small, portable and inexpensive," Wang said. "This system used plasmonic nanocrystals that act somewhat like a tiny lens, to concentrate a light wave and increase sensitivity."

This approach is combined with a metal-organic framework of thin films, which can rapidly adsorb gases within material pores, and be recycled by simple vacuum processes. After the thin film captures the gas molecules near the surface, the plasmonic materials act at a near-infrared range, help magnify the signal and precisely analyze the presence and amounts of different gases.

"By working at the near-infrared range and using these plasmonic nanocrystals, there's an order of magnitude increase in sensitivity," said Chih-hung Chang, an OSU professor of chemical engineering. "This type of sensor should be able to quickly tell exactly what gases are present and in what amount."

That speed, precision, portability and low cost, the researchers said, should allow instruments that can be used in the field for many purposes. The food industry, for industry, uses carbon dioxide in storage of fruits and vegetables, and the gas has to be kept at certain levels.

Gas detection can be valuable in finding explosives, and new technologies such as this might find application in airport or border security. Various gases need to be monitored in environmental research, and there may be other uses in health care, optimal function of automobile engines, and prevention of natural gas leakage.

Fighting cancer and Ebola with nanoparticles

Story highlights Scientists in the U.S. are applying nanotechnology research to the battle against cancer and Ebola Man-made nanostructures would attach themselves to viruses or cancerous cells, nullifying them Nanostructured surfaces are already in use for medical conditions and implants, reducing the risk of infection

From targeted remedies such as monoclonal antibodies to surgery, cancer has still managed to elude a treatment that discretely and separately attacks it alone.

Nanotechnologies, however - the manipulation of matter at a molecular and even atomic scale to penetrate living cells -- are holding out the promise of opening a new front against deadly conditions from cancer to Ebola.

According to Dr Thomas Webster, the chair of chemical engineering at Northeastern University in Boston, research into medical nanotechnology is gaining pace and the medical establishment is starting to sit up and pay attention.

At the core of the technology is the ability to attach drugs, and in some cases metals and minerals, to nanoparticles that would then bind themselves to life threatening cancer cells or viruses.

In one study, Dr Webster's team is developing methods to attach gold nanoparticles to cancer cells.

Infrared light would then heat up the nanoparticles, killing the cancer cells with heat but leaving the healthy cells alive to do their job.

"This technology has been studied for the better part of a decade, but we're looking at ways of making it better," Dr Webster told CNN. "One that we've created in the lab we've called 'nanostars.'

"A star shape has a lot more surface area, so they can kill cancer cells faster than a nanosphere because they heat up faster.

"Even if it's carrying a drug, a star has a lot more surface area on which to attach it -- it's got a different morphology."
