Self-assembly of hydrophobically modified naphthalene-labeled poly(acrylic acid) polyelectrolyte in water: Organic solvent mixtures followed by steady-state and time-resolved fluorescence

Article Abstract:

An investigation is conducted on the solution properties of two water-soluble polymers, poly(acrylic acid) (PAA) in water:organic solvent mixtures. Fluorescence measurements were used to follow the photophysical behavior of the polymers and consequently report on the self-association of the polymers in the mixed organic aqueous solutions.

Dynamics and energetics of the self-assembly of a hydrophobically modified polyelectrolyte: Naphthalene-labeled poly (Acrylic acid)

Article Abstract:

Studies of steady-state and time-resolved fluorescence are performed on aqueous solutions of poly(acrylic acid), which is hydrophobically modified, with two very different levels of naphthalene. It is demonstrated that unique information can be obtained on association of the phenomena involving hydrophobe-modified polymers.

Responsive polymer gels: double-stranded versus single-stranded DNA

Article Abstract:

The studies related to the gels of both single and double-stranded DNA which were found to exhibit differences due to difference in linear charge density, chain flexibility and hydrophobicity are presented.
