Scientist Stitch Nerves with BioAdhesives

Scientists have succeeded in regenerating the severed nerves of rats using a specially designed bioadhesive.

The gel, made from pigs’ bladder cells interlaced with molecules found in the regenerated limbs of Mexican walking fish, could become a breakthrough method for repairing damaged nerves and spinal cord injuries in humans.

A biomedical engineer and the lead inventor of the bioadhesive, Helder Marcal, said there was currently no way to regenerate injured nerves.

”You can stitch a nerve together but that would not give you recovery or regeneration and most of the time a patient will lose the capacity to move that limb,” Dr Helder, from the recently launched Australian Centre for Nanomedicine at the University of NSW, said.

BiomedicalCybernetics- A Biomedical Field

Biomedical Cybernetics is an innovative scientific approach that aims in a deeper understanding of function and development of complex living systems. It covers mathematical and structural description of information processing in organisms and ecosystems, decision making, e.g. in clinical application and statistical description of dynamical networks that describe e.g. the spreading of infectious diseaes.

Subject of biological cybernetics is the investigation of navigational principles that are essential for survival as well as reproduction of organisms. Being understood in the broadest possible sense the term “organism” covers all possible scales ranging from single organelles to the biosphere.

What is Medical Bionics?

Medical Bionics Abstract.jpg

Medical bionics is the replacement or monitoring of damaged organs through engineered devices that interface with the body to improve health outcomes. In this presentation I will concentrate on medical bionic devices designed to restore or supplement function of the nervous system lost during disease or injury.

A number of commercially available neural prostheses will be described – including the remarkably successful bionic ear and deep brain stimulation for movement control.

I will then review some of the current research performed around the world – including recent developments in brain-machine interface that will ultimately allow patients to control prosthetic limbs and wheel chairs; developments in functional electrical stimulation for gait and standing in paraplegia; and research to develop a prosthetic balance system.


Biomedical Engineers these days are mostly recruited in the hospitals around the globe. So other than the specific knowledge about the abc’s of electronics awareness about patient monitoring is also required for the Biomedical Engineers , So keeping in mind that fact here I have introduced a article which one of my friend contributed from his place. This article or document was prepared by Mahmoud faroug during his studies and must be appreciated for his contribution to BIOMEDIKAL.IN

Plasma is the fourth state of matter. Many places teach that there are three states of matter; solid, liquid and gas, but there are actually four. The fourth is plasma. To put it very simply, a plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist.


The DOE Artificial Retina Project is a multi-institutional collaborative effort to develop and implant a device containing an array of microelectrodes into the eyes of people blinded by retinal disease. The ultimate goal is to design a device with hundreds to more than a thousand microelectrodes. This resolution will help restore limited vision that enables reading, unaided mobility, and facial recognition.

The device is intended to bypass the damaged eye structure of those with retinitis pigmentosa and macular degeneration. These diseases destroy the light-sensing cells (photoreceptors, or rods and cones) in the retina, a multilayered membrane located at the back of the eye.
