Summary

Chitin and lignin are by-products of the fishing and plant-processing industries, and at the nanoscale both display antimicrobial and anti-inflammatory activity. Because their polarities differ, chitin nanofibril and nanolignin can be assembled into micro-complexes able to carry bioactive compounds such as glycyrrhetinic acid. This study electrosprays those complexes onto electrospun polyhydroxyalkanoate fibre meshes, combining two processes on one machine: the fibre provides the structure, the sprayed complex provides the function.

Linari Electrospinning Systems

Linari electrospinning / electrospray system
The meshes were produced on a Linari Engineering S.r.l. system (Pisa, Italy), with electrospray carried out for 20 minutes onto a grounded static aluminium collector 10 cm from the needle. Running both electrospinning and electrospray on one machine is a standard capability of our complete stations.
