Tiny electric generators could accelerate wound healing
 |
The natural wound healing process involves complex interactions between ions, cells, blood vessels, genes and the immune system; with every player triggered by a sequence of molecular events. An integral part of this process involves the generation of a weak electric field by the damaged epithelium - the layer of cells covering tissue. The electric field forms as a result of an ion gradient in the wound bed, which plays an important role in directing cell migration and promoting blood vessel formation in the area.
Scientists discovered in the mid- to late-1900s that stimulating tissue with an electric field could improve wound healing. Current research in this field is now focused on developing small, wearable, and inexpensive patches that aren't encumbered by external electrical equipment.
This has led to research on piezoelectric materials, including natural materials like crystals, silk, wood, bone, hair and rubber, and synthetic materials such as quartz analogs, ceramics and polymers. These materials generate an electric current when exposed to mechanical stress. Nanogenerators developed using the synthetic materials are especially promising.
For example, some research teams are exploring the use of self-powered piezoelectric nanogenerators made with zinc oxide nanorods on a polydimethylsiloxane matrix for accelerating wound healing. Zinc oxide has the advantage of being piezoelectric and biocompatible. Other scientists are using scaffolds made from polyurethane and polyvinylidene fluoride (PVDF) due to their high piezoelectricity, chemical stability, ease of manufacturing and biocompatibility. These and other piezoelectric nanogenerators have shown promising results in laboratory and animal studies.
Another type of device, called a triboelectric nanogenerator (TENG), produces an electric current when two interfacing materials come into and out of contact with each other. Scientists have experimented with TENGs that generate electricity from breathing movements, for example, to accelerate wound healing in rats. They have also loaded TENG patches with antibiotics to facilitate wound healing by also treating localized infection.
"Piezoelectric and triboelectric nanogenerators are excellent candidates for self-assisted wound healing due to their light weight, flexibility, elasticity and biocompatibility," says bioengineer Zong-Hong Lin of the National Tsing Hua University in Taiwan. "But there are still several bottlenecks to their clinical application."
For example, they still need to be customized so they are fit-for-size, as wound dimensions vary widely. They also need to be firmly attached without being negatively affected or corroded by the fluids that naturally exude from wounds.
"Our future aim is to develop cost-effective and highly efficient wound dressing systems for practical clinical applications," says Lin.

ROSE Technical Analysis: Exodus of Sellers Extinguish Positive Demand
ROSE coin price fails to sustain above $0.50 and falls to the horizontal level at $0.45. Will the $0.45 level collapse under high selling pressure? Oasis Network (ROSE) is a security-focused level one blockchain developed to promote the open economy of finance as well as a responsible and sustainable data economy that utilizes the Cosmos SDK. Oasis is a leader in applications that encourage security and privacy of data and hopes to enable the private, scalable Defi and to expand beyond traders to the market. It is able to achieve high speed and has a secure structure by separating the settlement as well as the consensus layers. Let us move ahead to read about Oasis Network technical analysis. Past Performance of ROSE The ROSE coin price shows a downfall of almost 15% in the past 72 hours resulting in the formation of multiple bearish candles in the daily chart. The higher price rejection is evident by the long wick formations in the daily candles indicating a rise in selling pressure. Furthermore, the 25% jump in the trading volume indicates the entry of more sellers into the market. ROSE/USD Daily Chart ROSE Technical Analysis The retracement in the ROSE coin price can be a retest of the bullish breakout of $0.45. However, the increased trend momentum and rising selling pressure undermine the possibility of a retest. Nonetheless, the horizontal level at $0.45 remains a crucial milestone in ROSE coin price action providing resistance multiple times before. Therefore, the level can halt the falling prices for a while. Crucial EMAs (50, 100, and 200) in the daily chart maintain a bullish trend in a positive alignment ready to provide support to the downfall. Therefore, dips at 50-day EMA can generate a buying opportunity. The RSI indicator at 59% shows a fall in the slope from the overbought zone in the daily chart. The slope keeps a negative trend as it gives a bearish crossover with 14-day EMA and approaches the central mark. The MACD indicator shows the MACD line approaching the signal line to give a bearish crossover. Moreover, the falling distribution of the bullish histograms indicates a rise in selling pressure. In short, the technical indicators reflect a fall in buying pressure and the price action showcases the entry of sellers. Therefore, the possible fallout of $0.45 will generate excellent selling pressure. Upcoming Trend The failure to sustain above the $0.50 mark drives the ROSE coin price lower to the horizontal level at $0.45. However, the increasing pressure projects a high possibility of a fallout below it. However, being a crucial price action level, traders need to keep their eyes out for bullish reversal. This is why holders should avoid selling under pressure and wait for the price action confirmation. Moreover, a reversal from $0.45 can drive the prices higher to create new all-time high levels. The ROSE coin price chart suggests the next support levels at $0.41 and the 50-day EMA. And, in case of a bullish reversal, the price can find support at $0.55 and $0.65. The technical analysis by tradingview showcases a “NEUTRAL” sentiment in daily timeframe at press time. Technical Analysis for ROSEUSD by TradingView
