• reciprocating tribometer with a velocity 1 mm/s and at a normal load of 50 mN for 3000 cycles. Contact-angle measurements The apparent contact angles were measured for various samples. Measurements were made with a Rame-Hart automated goniometer model 290-F4, where 5 μL water droplets were deposited onto the

• [13]. The gold nanoparticle was shown to dramatically quench the optical lifetime of the QD and to completely suppress its blinking. Experimental In this work, we position a single fluorophore, a CdSe QD, with nanometre precision on a macroscopic registration template, using automated atomic force

• first sequencing methods were published in 1977 by Maxam and Gilbert [1], and Sanger et al. [2]. Since then the sequencing technology has been refined and automated, and current advances show a tendency towards single-molecule sequencing, which eventually results in the development of sequencing systems

Reestablishment of the native α-amide peptide backbone can be achieved by an increase in the pH to neutral or even slightly basic conditions. The peptide segment was obtained by a semi-automated solid-phase supported peptide synthesis
