Abstract: Microporous polyamide-6 membranes were hydrolyzed in 0.01mol/L NaOH/CH3OH medium by refluxing for about 36h.By investigating the UV spectra, the hydrolyzing conditions were optimized.ApH value of 12 and reaction time of 36h are the preferred conditions for hydrolysis.The treated membrane can be applied for in site synthesis of oligonucleotide and, for example, the oligonucleotide probes of 5′-AACCACCAAACACAC-3′ were successfully synthesized on the hydrolyzed membrane,which was proved by the high resolution X-ray photoelectron spectroscopy(XPS) of P2pThe single step coupling efficiency was determined by UVspectra to be in excess of 98%.

Key words: Catalytic hydrolysis, Amino group, Nylon-6 membrane, DNA in site synthesis, Coupling efficiency
