Todd Hoare, PhD | Scientific Advisor

Dr. Todd Hoare is the Canada Research Chair in Engineered Smart Materials and a Professor in the Department of Chemical Engineering at McMaster University. Dr. Hoare’s work on “smart” environmentally-responsive hydrogels, in situ-gelling/printable hydrogel materials, and nanoscale drug delivery vehicles has been profiled by Popular Science, Maclean’s, and BBC for its potential in solving clinical challenges through innovative materials design. He has published >100 papers and holds 7 patents which have led to four license agreements and one spin-off company. 


All things PolyZen™

Find out more about PolyZen™ and its uses.

Degradation of cartilage and synovial fluid in the joints that prevents friction between the bones leading to constant pain & limited joint movement. Over 242M people are currently living with symptomatic and activity-limiting osteoarthritis (OA).

Current treatment options are inadequate:

  • Pain medication – only provides temporary pain management
  • Orthotics/Knee braces – discomfort & mixed results
  • Total joint replacement – invasive, costly and an end of the line necessity
  • Viscosupplementation (Intra-articular injections) – effective but degrades quickly

PolyZen™ is a zwitterionic in situ gelling hydrogel.

  • The zwitterionic component provides excellent antifouling properties that lead to high lubrication that mimics native and healthy synovial fluid
  • The in-situ gelling mechanism allows us to tailor physiochemical properties such as degradation rate and compressive strength
  • This combination of properties allows for both lubrication and mechanical support that is otherwise unavailable in a single package

Synovial Fluid

PolyZen™ exhibits the same fluid properties as healthy and natural synovial fluid & provides lubrication even under severe OA simulations.

Tunable viscosity to match synovial fluid viscosity ranges

Significantly better lubrication than leading hyaluronic acid-based viscosupplements


The elasticity of PolyZen™ hydrogels can be customized to levels closer to the human cartilage compared to the HA-based hydrogels
