Tattoo-like Sensors Reveal Blood Oxygen Levels

Engineers have invented a silk-based material that when placed under the skin that glows brighter or dimmer under a lamp when exposed to different levels of oxygen in the blood. The novel sensor, which currently is limited to reading oxygen levels, is made up of a gel formed from the protein components of silk, called fibroin. The silk fibroin proteins have unique properties that make them especially compatible as an implantable material.

Silk's Unique Properties Present Possibilities for Future Technologies

Silk makes an important biomaterial, because it does not generate an immune response in humans and promotes the growth of cells. It has been used in drug delivery, and because the material is flexible and has favorable technological properties, it is ideal for wearable and implantable health monitoring sensors.

Scientists Create the Next Generation of Living Robots

Last year, a team of biologists and computer scientists created novel, tiny self-healing biological machines from frog cells called "Xenobots" that could move around, push a payload, and even exhibit collective behavior in the presence of a swarm of other Xenobots. The same team has now created life forms that self-assemble a body from single cells, do not require muscle cells to move, and even demonstrate the capability of recordable memory.

CRISPR Treatment Cuts Cholesterol in Mice by Up to 57% in one Shot

The genome editing technology CRISPR has emerged as a powerful new tool that can change the way we treat disease. The challenge when altering the genetics of our cells, however, is how to do it safely, effectively, and specifically targeted to the gene, tissue and organ that needs treatment.

Bioelectronic Device Achieves Unprecedented Control of Cell Membrane

In an impressive proof-of-concept demonstration, an interdisciplinary team of scientists has developed a bioelectronic system driven by a machine learning algorithm that can shift the membrane voltage in living cells and maintain it at a set point for 10 hours.

Smart Fabrics From Bioactive Inks

Researchers have developed biomaterial-based inks that respond to and quantify chemicals released from the body (e.g. in sweat and potentially other biofluids) or in the surrounding environment by changing color. The inks can be screen printed onto textiles such as clothes, shoes, or even face masks in complex patterns and at high resolution, providing a detailed map of human response or exposure.

The First Living Robots

A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need. Now a team of scientists has repurposed living cells—scraped from frog embryos—and assembled them into entirely new life-forms. These millimeter-wide "xenobots" can move toward a target, perhaps pick up a payload (like a medicine that needs to be carried to a specific place inside a patient)—and heal themselves after being cut.

Noninvasive neuromodulation to treat obesity

Novel approaches that have been tested to treat obesity include noninvasive neuromodulation techniques such as transcranial direct current stimulation. Studies performed to date have suggested that this method does in fact help reduce appetite, food intake and body weight, but only in some subjects.

Flexible electronics and smart bandages are key to cost savings

Flexible electronics and smart bandages are key to cost savings in the future of advanced wound care. Advanced wounds, referring to those that are non-healing for more than 4 weeks, are on the rise around the world. This is because there are an increasing number of people with poor wound healing ability, including the rising number of elderly people over 65 years of age, and the rising number of people with Type 2 diabetes.
