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.

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.

3D printing electronics and cells directly on skin

3D printing electronics and cells directly on skin
In a study, researchers at the University of Minnesota used a customised, low-cost 3D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics. Researchers also printed biological cells on the skin wound of a mouse. The technique could lead to medical treatments for wound healing and direct printing of grafts for skin disorders.

3D printing lifelike artificial organ models

3D printing lifelike artificial organ models
A team of researchers led by the University of Minnesota has 3D printed lifelike artificial organ models that mimic the exact anatomical structure, mechanical properties, and look and feel of real organs. These patient-specific organ models, which include integrated soft sensors, can be used for practice surgeries to improve surgical outcomes in thousands of patients worldwide. The research was published in the journal Advanced Materials Technologies. The researchers are submitting a patent on this technology.

3D-printed patch helps mend a broken heart

3D-printed patch helps mend a broken heart
A team of biomedical engineering researchers, led by the University of Minnesota, has created a revolutionary 3D-bioprinted patch that can help heal scarred heart tissue after a heart attack. The discovery is a major step forward in treating patients with tissue damage after a heart attack. The research study is published in Circulation Research, a journal published by the American Heart Association. Researchers have filed a patent on the discovery.
