Chemists seek light-activated glue for vascular repair

31.03.2004


Surgeons battle time and the body’s defenses as they stitch together veins and arteries, whether after an injury or in the course of such treatments as transplants or bypasses. Loss of blood before a site is closed and too much clotting soon after challenge medical care.

Virginia Tech researchers are creating biocompatible adhesives for use with vascular tissue that will speed the process of mending tissue. They will present the research at the 227th annual meeting of the American Chemical Society in Anaheim, Calif., March 28 through April 1, 2004.

The goal is to make it possible for surgeons to splice, reattach, or mend vascular tissue by applying a biopolymer coating and activating it with light, such as a laser, explains Timothy Long of Blacksburg, professor of chemistry in the College of Science at Virginia Tech. Another use would be as a stable, easy-to-use material that medics could apply to stop bleeding and prevent clotting.



Chemistry doctoral student Afia S. Karikari will explain the structure and characteristics of the novel polymer, how light causes it to change shape and function, and what the researchers have determined about the properties of several compounds that are candidates for a material that could make laser assisted vascular repair possible.

Karikari, a Packard Fellow, is a graduate of Clark Atlanta University. A native of Ghana, West Africa, she moved to the United States with her family and attended Pebblebrook High School in Mableton, Ga.

She will present the paper, "Photocrosslinking of star-shaped poly(d,l-lactide)s containing an ethoxylate core (Poly 368)" at 8:50 a.m. Tuesday, March 30, 2004, in the Garden B room of the Anaheim Coast Hotel. Co-authors are Craig Thatcher, professor and department head of large animal clinical sciences in the Virginia–Maryland Regional College of Veterinary Medicine, and Long.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
