Unless otherwise stated, all solvents and reagents were purchased from Sigma-Aldrich, Fisher Scientific UK, Alfa Aesar (Heysham, UK), Acros Organics (Geel, Belgium), or VWR International (Lutterworth, UK) and used without further purification. Deionized water was produced using a Milli-Q purification system. 1H and 13C NMR Spectra were recorded on a Bruker AVA500 spectrometer operating at 500.12 and 125.76 MHz for 1H and 13C, respectively. 71Ga NMR spectra were recorded on a Bruker PRO500 spectrometer at 152.55 MHz.
Pro500 spectrometer
Manufactured by Bruker
The PRO500 spectrometer is a high-performance analytical instrument used for nuclear magnetic resonance (NMR) spectroscopy. It is designed to provide precise measurements and analysis of molecular structures and compositions. The core function of the PRO500 is to generate and detect radio frequency signals to study the magnetic properties of atomic nuclei in chemical samples.

2-Bromo-2-methyl-propionic acid benzyl ester initiator was synthesized as previous described. [35] Ethyl acrylate (EA) (99%, Acros) and dimethylamino ethyl acrylate (DMAEA) (98%, Sigma-Aldrich) was passed over a short-column of basic Al2O3 before use in order to remove the radical inhibitor. NMR experiments were carried out on a Brüker Pro500 spectrometer. Molar mass distributions were measured by size exclusion chromatography (SEC), on a system equipped with two Polymer Laboratory GPC columns (PL gel 5 μm mixed D-columns, 300 x 7.5 mm) and one PL gel 5 μm guard column (50 x 7.5 mm) (Polymer Laboratories, suitable for molecular weights between 200 and 400,000 g mol -1 ) with differential refractive index detection using N, N-dimethylformamide (DMF) / 0.1M LiBr at 1 mL min -1 as the eluent with the temperature set at 60 ºC. Poly(MMA) standards were used to calibrate the SEC. Cell imaging was carried out on a Zeiss semi-confocal microscope, with cell culture reagents purchased from Invitrogen unless otherwise stated.
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.
