Natural antibodies are able to recognize molecules with remarkable affinity and specificity. However, beyond of their high cost, they are very sensitive and can denature at harsh conditions.
Traditional approaches to mimic natural antibodies involves the use a lot of organic solvents and in the end of the process, the material produced need to be ground, destroying partially the affinity sites created within the material
Green plastic antibodies are produced using a green technology, supercritical carbon dioxide (scCO2), as a free-flowing polymer powder capable of keeping the same features of natural antibodies as affinity and selectivity with key advantage that can be used in a variety of extreme conditions without degradation in a wide range of processes, since sensors, enrichment, drug delivery, separation, purification and catalysis.
