Summary
CardioGenics’ silver-coated paramagnetic beads (the “CardioGenics Beads”) represent a significant product advance over current similar commercial products. All commercial magnetic beads are made of dark iron oxide. CardioGenics has developed a proprietary process to plate magnetic beads with a layer of silver, making them white, and more sensitive to light. In testing against all commercially available beads, the CardioGenics Beads demonstrated a seven-fold improvement in light harvesting, which results in improved testing sensitivity.
Market Background
► Due to simplicity in use and ease of manipulation, magnetic particles are the preferred solid phase for immobilizing biological material used in test kits developed for:
- Clinical laboratory testing analyzers (immunoassays/DNA binding)
- Life sciences research market
- Cell & nucleic acid separation
- Protein purification
- Sample enrichment
► Market of Magnetic Beads
- Global In Vitro Diagnostic (IVD) market estimated at $22.9 billion in 2002
- Expected growth of the IVD is 7% per year
- Immunoassay testing segment of this market is 40%
- About 90% of the immunoassay analyzers employ both magnetic particles and light measurements
- Estimated magnetic beads market is about $1 billion for immunoassay only (3rd party market report)
► Magnetic Beads Producers
- Several companies commercialize magnetic particles for biomedical research and in-vitro diagnostic applications
- All commercial products contain dark iron oxide material
- Current commercial manufacturing processes is by encapsulation of magnetic pigment inserted in a latex particle
- Three (3) main players, led by Merck Chimie, several small ones
- Prices range from $900-1500/gram of solids
► The CardioGenics Beads
- A 24 month developmental process supported by grants from National Research Council of Canada (NRC), 4 in total
- Proprietary silver-plating process, adapted to various sizes (1-50 micron) beads
- CardioGenics Beads plated with silver for color conversion (Black to White)
- CardioGenics Beads are then polymer encapsulated
- CardioGenics developed its own polymer encapsulation process
- CardioGenics also produced beads to be encapsulated by its partner through their proprietary polymer encapsulation process
- CardioGenics encapsulated beads are manufactured by a simplified process
- Beads encapsulated by CardioGenics will be processed in batch sizes of “commercial lots”

Competitive Advantages
► Current commercial beads suffer from the following shortcomings:
- All commercial magnetic particles are dark
- About 80% of generated light, is lost which results in low testing sensitivity
- The manufacturing process is complicated and expensive
► The CardioGenics Beads offer the following advantages:
- Maximize light collection by white color conversion
- High magnetic moment, easy manipulation
- Chemically-robust surface chemistry
- Simplified manufacturing process-- less costly
- Compared with beads of all major suppliers, the CardioGenics Beads show consistent ~7 fold improved light signal to address needs of IVD industry for more sensitive tests (published data).
Market Advantage
►Applications that would benefit from:
- Increased test sensitivity by at least ~5 fold, early diagnosis
- Easy sample manipulation
- Custom-made linking chemistry
Potential End Users
►Clinical In-Vitro Diagnostics test developers
- Ten (10) first tier global IVD test manufacturers
- Thirty (30) second tier IVD test manufacturers
- Numerous small regional manufactures
►Life sciences research applications, companies/universities
Future Markets:
- Proteins/ DNA Binding
- Cell sorting
- Nanoreactors
- Adaptation to POC/other instruments (non-competitive)
