The monomers used were 2-(dimethylamino) ethyl methacrylate (DMAEMA) (98%), lauryl methacrylate (LMA) (96%) and (oligo ethylene glycol) methacrylate (OEGMA, average Mn = 475) from Sigma-Aldrich (St. Louis, MO, USA). They were purified by passing through an inhibitor removing mini column. Resins used were 311,340 and 311,332 from Sigma-Aldrich. The 2,2-azobis(isobutyronitrile) (AIBN) was the radical initiator utilized after recrystallization from methanol. The 1,4-dioxane (99.8% pure), from Aldrich, was dried over molecular sieves before use. Tetrahydrofuran (THF, 99.9% pure), 4-cyano-4-(phenylcarbonothioylthio) pentanoic acid (CPAD), fetal bovine serum (FBS) and other reagents from Aldrich were used as received.

Polycaprolactone (M n = 80 kg mol À1 ), oligoethylene glycol methacrylate (OEGMA) with an average molecular weight of 475 (methyl ether termination), 2,2 0 -bipyridine, CuBr, NaCl, NaH 2 PO 4 and Na 2 HPO 4 were obtained from Sigma Aldrich. Prior to use, CuBr was purified by washing three times with glacial acetic acid, twice with absolute ethanol and twice with diethyl ether followed by drying in a vacuum oven overnight. KF (anh.), Na 2 EDTA, CuSO 4 and ascorbic acid were acquired from BDH. Fetal bovine serum was purchased from Life Technologies. The protected alkyne monomer, TMS-propargyl-hexaethylene glycol methacrylate (TMS-Prg-HEGMA), 40 the click reaction ligand, tris((1-(4-carboxybenzyl)-1H-1,2,3-triazol-4-yl)methyl)amine) (TBTA-COOH), 41 and the fluorinated azide labelling molecule, 2,2,2-trifluoroethyl 4-(azidomethyl)benzoate (TFAB), 31 were synthesised as previously reported. A cyclic RGD peptide, cyclo(Arg-Gly-Asp-D-Phe-Lys(azide)) was obtained from Peptides International (Louisville, KY, USA). All solvents (chloroform, methanol, ethanol (96%), DMF, DMSO and toluene) were reagent grade unless specified and obtained from Merck. All water was purified and deionised using a MilliQ system (Millipore).
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.
