This is our platform product in development. Simply put, we place polymer-coated beads inside a system that’s designed for filtration. This could be cartridges, filtration columns, filter beds, or other similar systems. If we make sure that the target molecules come into contact with the polymer (and enough polymer to capture all of the target molecules), then the capture is instant and extensive. As we are working with beads, the fluids can be pumped through at high pressures if high flow rates are required.
Our polymers can be grown or coated on other materials, a good example being our coated beads. Coatings can range from nanometer scale through to hundreds of microns, which means that it should be possible to create products with woven MIP-coated fibres. Polymers that are grown on a surface will be very robust. The list of target materials is broad – we’ve even bound to Teflon.
Fibres / filters
We have been working with Revolution Fibres in Auckland on embedding imprinted polymers into nanofibres. The results so far are very promising. Molecularly imprinted nanofibres will enable us to produce filtration media for both fluids and air, with massive surface area providing very high capture rates of target molecules.
Volume, flow, pH and temperature
Each of our polymers is build from scratch and optimised for the target environment. This maximises the capture rate and minimises the amount of polymer that is required.
Volume – the amount of target material, which we’ve had ranging from grams per litre to parts per billion.
Flow – high speed and pressure flows are fine for the polymer.
pH – we’ve designed polymers to work and endure at both extremes – they are highly robust.
Temperature – somewhere between 0 and 50 degrees C has been the typical temperature for the target fluids (from our industrial development partners) and this is perfect for the polymer. In fact, it’s likely that the polymers will be stable up to 300 degrees C.
The design, testing and piloting process is quick, ranging from a few weeks for very familiar targets in a familiar environment (such as an additional agrochemical to be removed from wine) to 6 to 9 months for a completely unfamiliar process.
