Polysaccharides have a spectacular range of properties which stem from the relationships between the chemical nature of the sugars, their arrangement within the polymer and the arrangement of the polymer itself. They appear in every corner of the natural world and have multiple applications in nature ranging from protection to energy storage. Not surprisingly humanity has taken advantage of their diversity and by doing so created a huge variety of uses within the medicinal, material and consumable sectors. We invite you to take a brief look at what we believe could one day be possible if a system to design bespoke polysaccharides existed. Alex Clowsley, 2012. |
