We propose a method for the modification of surfaces of microchannels in chips fabricated in polycarbonate (PC) that makes the devices resistant to a range of organic solvents. Coating of PC with branched polyethyleneimine (BPEI) with the use of trimethylpropane triglycidyl ether (TTE) as a linker renders the devices resistant to toluene, benzene, acetonitrile, tetrahydrofuran, dioxane and ethy...

The valorization of natural polymeric substrates has increased due to their uses and applications in several fields. existence many functional groups chemical structures allows them be easily subjected modifications. This work focuses on the exploration a new low-cost abundant cellulosic biomass, Zilla spinosa fruit. biomaterial was functionnalized with polyethyleneimine (1%, 3%, 5%, 8%) order ...

Currently, the most severe limitation to applying RNA interference technology is delivery, including localizing the molecules to a specific site of interest to target a specific cell population and sustaining the presentation of these molecules for a controlled period of time. In this study, we engineered a functionalized, biodegradable system created by covalent incorporation of cationic linea...
