Using biosensors to deliver personalised doses of antibiotics

Using biosensors to deliver personalised doses of antibiotics
A team of eight EPFL students has come up with a portable biosensor that can measure the amount of vancomycin in a patient’s blood stream, enabling doctors to better control the dosage and reduce harmful side effects. Their technology – developed for the upcoming SensUs international competition – could eventually be used for other antibiotics as well. At EPFL’s Discovery Learning Labs (DLL) – educational facilities designed to promote cross-disciplinary research – a groundbreaking new device is in the works.

The latest protocol for creating human cortical organoids

The latest protocol for creating human cortical organoids
Writing in the current online issue of the journal Stem Cells and Development, researchers at University of California San Diego School of Medicine have described development of a rapid, cost-effective method to create human cortical organoids directly from primary cells. Experimental studies of developing human brain function are limited. Research involving live embryonic subjects is constrained by ethical concerns and the fragile nature of the brain itself.

The alchemy of healing: turning open wounds into skin

The alchemy of healing: turning open wounds into skin
Plastic surgery to treat large cutaneous ulcers, including those seen in people with severe burns, bedsores or chronic diseases such as diabetes, may someday be a thing of the past. Scientists at the Salk Institute have developed a technique to directly convert the cells in an open wound into new skin cells. The approach relies on reprogramming the cells to a stem-cell-like state and could be useful for healing skin damage, countering the effects of aging and helping us to better understand skin cancer.

Fully 3D printed prototype for ‘bionic eye’

Fully 3D printed prototype for ‘bionic eye’
A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a 'bionic eye' that could someday help blind people see or sighted people see better. The research is published in Advanced Materials, a peer-reviewed scientific journal covering materials science. The author also holds the patent for 3D-printed semiconducting devices.

Magnetic gel can be used to ease pain

Magnetic gel can be used to ease pain
UCLA bioengineers have demonstrated that a gel-like material containing tiny magnetic particles could be used to manage chronic pain from disease or injury. Broadly, the study demonstrates the promising use of biomechanical forces that push and pull on cells to treat disease.

3D-printed placenta simulates structure of membrane

3D-printed placenta simulates structure of membrane
In order to better understand important biological membranes, it is necessary to explore new methods. Researchers at TU Wien (Vienna) have succeeded in creating an artificial placental barrier on a chip, using a high-resolution 3D printing process. The placenta has an essential and highly complex task: it must ensure the exchange of important substances between the mother and her unborn child, whilst simultaneously blocking other substances from passing through.

Developing new ways to grow blood vessels

Developing new ways to grow blood vessels
Formation of blood vessels, a process also known as angiogenesis, is one of the major clinical challenges in wound healing and tissue implants. To address this issue, researchers from Texas A&M University have developed a clay-based platform to deliver therapeutic proteins to the body to assist with the formation of blood vessels. The team is led by members of the Inspired Nanomaterials and Tissue Engineering Lab in the Department of Biomedical Engineering.

Conductive mesh for implantable and wearable bioelectronics

Conductive mesh for implantable and wearable bioelectronics
A research team at the Center for Nanoparticle Research, within the Institute for Basic Science (IBS), has succeeded in developing a wearable and implantable device, that measures electrophysiological signals and applies electrical and thermal stimulations. It provides information on muscle and cardiac dysfunctions, and thus could be implemented for pain relief, rehabilitation, and prosthetic motor control.

Feeling as if a prosthetic limb belonged to one's body

Feeling as if a prosthetic limb belonged to one's body
Amputees still feel their missing limb, even if it is physically gone, and this ghost limb aka phantom limb is perceived as much smaller that the lost limb. Next, the commercially available prosthetic limb does not yet provide sensory feedback other than what the patient sees, meaning that the patient has no sense of touch from the prosthetic limb and must constantly watch it for correct use.

3D-printed device could help treat spinal cord injuries

3D-printed device could help treat spinal cord injuries
Engineers and medical researchers at the University of Minnesota have teamed up to create a groundbreaking 3D-printed device that could someday help patients with long-term spinal cord injuries regain some function. A 3D-printed guide, made of silicone, serves as a platform for specialised cells that are then 3D printed on top of it. The guide would be surgically implanted into the injured area of the spinal cord where it would serve as a type of 'bridge' between living nerve cells above and below the area of injury.
