Classification of analytics, sensorics, and bioanalytics with polyelectrolyte multilayer capsules [PDF]

open access: yes, 2020
Polyelectrolyte multilayer (PEM) capsules, constructed by LbL (layer-by-layer)-adsorbing polymers on sacrificial templates, have become important carriers due to multifunctionality of materials adsorbed on their surface or encapsulated into their ...
