Octopus-inspired sucker transfers thin, delicate tissue grafts, biosensors

October 20, 2020

Thin tissue grafts and flexible electronics have a host of applications for wound healing, regenerative medicine and biosensing. A new device inspired by an octopus’s sucker rapidly transfers delicate tissue or electronic sheets to the patient, overcoming a key barrier to clinical application, according to researchers at the University of Illinois at Urbana-Champaign and collaborators.

New IGB Theme Develops Engineered Living Systems with Novel Functionalities

May 11, 2020

For years, artificial systems - such as robots and machines - have been used for industrial applications, making a tremendous impact on society. However, steady progress made by scientists could see the replacement of artificial systems with “Multi-Cellular Engineered Living Systems” (M-CELS) composed of living cells and extracellular matrices organized to perform novel functions absent in natural systems.

Nanostimulators boost stem cells for muscle repair

May 1, 2020

In regenerative medicine, an ideal treatment for patients whose muscles are damaged from lack of oxygen would be to invigorate them with an injection of their own stem cells.

In a new study published in the journal ACS Nano, researchers at the University of Illinois at Urbana-Champaign demonstrated that “nanostimulators” – nanoparticles seeded with a molecule the body naturally produces to prompt stem cells to heal wounds – can amp up stem cells’ regenerative powers in a targeted limb in mice.

Injections, exercise promote muscle regrowth after atrophy in mice

April 29, 2019

By injecting cells that support blood vessel growth into muscles depleted by inactivity, researchers say they are able to help restore muscle mass lost as a result of immobility.

The research, conducted in adult mice, involved injections of cells called pericytes (PERRY-sites), which are known to promote blood vessel growth and dilation in tissues throughout the body. The injections occurred at the end of a two-week period during which the mice were prevented from contracting the muscles in one of their hind legs.

Smart antioxidant-containing polymer responds to body, environment

April 17, 2019

Oxidants found within living organisms are byproducts of metabolism and are essential to wound-healing and immunity. However, when their concentrations become too high, inflammation and tissue damage can occur. University of Illinois engineers have developed and tested a new drug-delivery system that senses high oxidant levels and responds by administering just the right amount of antioxidant to restore this delicate balance.

The findings are published in the journal Small.

Researchers develop microbubble scrubber to destroy dangerous biofilms

September 20, 2018

Stiff microbial films often coat medical devices, household items and infrastructure such as the inside of water supply pipes, and can lead to dangerous infections. Researchers have developed a system that harnesses the power of bubbles to propel tiny particles through the surfaces of these tough films and deliver an antiseptic deathblow to the microbes living inside.

Creating bio-machines to improve health

November 3, 2015

By studying the behavior of living cells and combining them with synthetic tissue, researchers are creating “biological machines” to deliver drugs more effectively, function as internal diagnostic tools, or serve as contaminant sensors in the field.

This work is facilitated by a multi-institution effort known as the Emergent Behaviors of Integrated Cellular Systems (EBICS), which recently received $25 million in National Science Foundation (NSF) renewal funding for the next five years to build living, multi-cellular machines to solve environmental, health, and security problems.

Illinois Chemical/Bioengineers Use Adhesion to Combine the Experimental Advantages of Silicones and Organic Materials

Introductory chemistry students learn that oil and water repel each other. So do other hydrophobic substances, which carry no electric charge, and hydrophilic substances, which carry an electric charge that allows them to mix with water.
