The effects of sucrose and fructose on the free energy of unfolding, ΔG N→D , and on the change in hydrodynamic radius, R H , upon unfolding were measured for RNase A and α-lactalbumin. Recently we analyzed the results for RNase A and showed that the effects of the carbohydrates on the protein's thermal stability can be accurately accounted for by scaled particle theory (SPT), and...
We demonstrate the sequence-specific patterning of nanoparticles via the hybridization of functionalized complementary probes to surface-bound stretched single chains of double-stranded DNA. Once these probes are in place, we attach the desired particles through molecular recognition with the probe’s functional group. This approach allows the assembly of any particle that can be coupled to a molecular...
Detailed calculations of the elastic, piezoelectric and pyroelectric properties of the β phase of poly(vinylidene fluoride) are reported. The calculations are based on an empirical atomistic force field that uses the shell model of electronic polarization. Quasi-harmonic lattice dynamics is used to include the vibrational entropy in the calculation of the crystal free energy. The equilibrium crystal...
