Minuscule Oxygen Sensing Implant can Measure Tissue Oxygen Levels in Real Time
Written by AZoSensorsApr 15 2021
A tiny wireless implant developed by engineers from the University of California, Berkeley, can offer real-time measurements of tissue oxygen levels deep beneath the skin.

The device is smaller than the average ladybug and driven by ultrasound waves. It could enable doctors to track the health of transplanted tissue or organs and offer an early warning of possible transplant failure.
A new tiny wireless implant provides real-time measurements of tissue oxygen levels deep underneath the skin.
The device, which is smaller than the average ladybug and powered by ultrasound waves, could help doctors monitor the health of transplanted organs or tissue and provide an early warning of potential transplant failure.
The technology also paves the way for the creation of a variety of miniaturized sensors that could track other key biochemical markers in the body, such as pH or carbon dioxide. These sensors could one day provide doctors with minimally invasive methods for monitoring the biochemistry inside functioning organs and tissues.

Compared to newborns conceived traditionally, newborns conceived through in vitro fertilization (IVF) are more likely to have certain chemical modifications to their DNA, according to a study by researchers at the National Institutes of Health. The changes involve DNA methylation the binding of compounds known as methyl groups to DNA which can alter gene activity. Only one of the modifications was seen by the time the children were 9 years old.
The study was conducted by Edwina Yeung, Ph.D., and colleagues in NIH s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). Previous studies by the research team found no differences in growth and development for this group.
