Syntetic blood subsitutes
Andrew Vreugdenhil ‐ Trent University
Abstract
This talk focuses on looking at BPA
through the eyes of a materials scientist.
Blood has many material properties
that can be reproduced by stable artificial
fluids. This plays an important role
in synthetic blood substitute (SBS) design
and fabrication. The listeners will
be taken through a descriptive discussion
on identifying key design features
of an ideal SBS, including everything
from longevity to matching key chemical
and physical behaviours of blood.
Our research group uses silicon colloid
chemistry to develop potential SBS candidates.
These candidate materials are
aqueous, room temperature, non-toxic
and stable colloidal solutions. They can
be made to incorporate chemical functionality
for emulating the behaviour of
blood to simulate forensic imaging and
biological analysis. There are many
ways to assess the performance of
these SBSs in comparison to blood, in
this talk, we focus on demonstrating
SBS performance during impact simulation
using high-speed video analysis.
Biography
Andrew Vreugdenhil currently is Director of the
Trent Materials Science graduate program and
the associated Centre for Materials Research at
Trent University in Peterborough, Ontario, Canada.
The Materials Science graduate program
specializes in the chemistry and physics of materials
to provide students with a broad physical
science understanding of modern materials
and their behaviour. Prof. Vreugdenhil holds a
Ph.D. in inorganic materials chemistry and is an
Associate Professor in the Trent University
Chemistry Department. His research program is
focused on the synthesis and characterization
of colloidal silicon hybrids. These colloidal materials
provide flexible, convenient, water-borne
chemistry appropriate for a wide range of applications.
These include formulation of environmentally
friendly crosslinked sol-gel coatings
systems, room temperature surface modification
and tailorable, stable and pathogen-free
synthetic blood substitutes for forensic research
and crime scene reconstruction.
