3D printed macroporous medical grade PCL scaffolds with porosity of 70% were purchased from Osteopore TM . Circular samples (12 mm diameter) were cut out of the 5 x 5 cm sheet using a metallic hole-puncher. PCL films (to be used for FTIR and contact angle measurements) were thermally pressed into a thickness of approximately 120 µm. Briefly, a known mass of PCL was placed between two stainless steel sheets on a Carver bench press (Carver Inc, USA). Temperature was elevated to 100 °C and pressure exerted for 30 min. The pressed film was then allowed to cool to room temperature via normal convection cooling.
Clevios™ CB 40 V2 (40% wt/wt Fe(III) p-toluenesulfonate (Tosylate) in butanol) was purchased from Heraeus (Germany). 3,4-Ethylenedioxythiophene (EDOT) monomer (142.18 g/mol), pyridine (79.10 g/mol), and the triblock copolymer poly(ethylene glycol)-block-poly(propylene glycol)-blockpoly(ethylene glycol) (PEG-PPG-PEG, 5800 g/mol) were purchased from Sigma-Aldrich. All chemicals were used as received without further purification.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
