nanobubbles

A small revolution in cancer treatment by Belarusian and U.S. scientists

Source: http://eng.belta.by/ Author: Igor Belotserkovsky Scientists from Belarus and the United States have developed a new method for detecting residual cancer cells. This method also contributes to their destruction. This is done with the help of nanobubbles generated in some cancer cells. The method was successfully tested on laboratory mice with implanted head and neck cancer cells. Although scientists are only at the beginning of the road, they call their discovery a small revolution in the fight against cancer. The results of the research titled “Intraoperative diagnostics and elimination of residual microtumors with plasmonic nanobubbles” was published in the prestigious science journal Nature Nanotechnology on 15 February. To learn more about the successes of oncologists, BelTA talked to Igor Belotserkovsky, PhD in Medical Sciences, one of the authors of the research, the leader of the head and neck tumor research team at the Aleksandrov National Cancer Center. Mr Belotserkovsky, what is the share of head and neck tumors in the structure of other localizations? In the total structure of oncological morbidity, the share of head and neck tumors is 3-4% (excluding skin cancer). Larynx and oral cavity cancer are diagnosed most frequently. For example, in 2014 laryngeal cancer was detected in 604 Belarusians, oro-pharyngo-laryngeal cancer in 1,338 people. Men fall ill ten times more often. Despite the fact that head and neck cancers are categorized as tumors of outside localization, many patients with cancer have their disease diagnosed when it has already reached an advanced stage. This is due to [...]

Laser and nanoparticles blow up cancer cells

Source: news.softpedia.com/ Author: Tudor Vieru In a new approach to fighting cancer cells, or cells ridden by several other types of diseases as well, researchers managed to combine the powers of lasers and nanoparticles most efficiently. The method relies on using short bursts of laser light to produce small explosions from gold particles that have been placed inside the targeted cells beforehand. The blasts, which cause no ill-effects to surrounding cells, are highly capable of dismembering the cancerous ones, acting like a “jackhammer” on their targets, and pounding relentlessly, LiveScience reports. Basically, the active elements in this therapy are nanobubbles, which form as the gold particles are subjected to intense, but short, laser pulses. The science group, which is based at the Rice University, was able to determine that the intensity of the lasers could be tuned in two ways, resulting in two different results. The end result could be either clear, bright and small bubbles, that were harmless, or larger explosions that took place inside the cell, which dismembered it. “Single-cell targeting is one of the most touted advantages of nanomedicine, and our approach delivers on that promise with a localized effect inside an individual cell. The idea is to spot and treat unhealthy cells early, before a disease progresses to the point of making people extremely ill,” says RU physicist Dmitri Lapotko. He was also the author of a new study detailing the method, which appears online, in the January 25 issue of the respected scientific journal Nanotechnology. [...]
