Self-assembled peptides and specifically small peptide based nanostructures have been the focus of research in past decade due to their potential biological applications. In this study, we prepared a protected peptide, Boc-Pro-Phe-Gly-OMe, which self-assembled in aqueous solutions leading to the formation of nanostructures and ability to act as a drug(More)
The present article focuses on the amphiphilic cationic polymers as antibacterial agents. These polymers undergo self-assembly in aqueous conditions and impart biological activity by efficiently interacting with the bacterial cell wall, hence, used in preparing chemical disinfectants and biocides. Both cationic charge as well as hydrophobic segments(More)
The present study demonstrates the use of self-assembled nanostructures of cationic amphiphilic azobenzene-neomycin (a small molecule) conjugate, Azo-Neo, as delivery vector for plasmid DNA. These nanostructures efficiently condensed nucleic acid and formed more compact nanoassemblies. DLS analysis showed size and zeta potential of the resulting(More)
Here, we have designed and synthesized a novel cationic amphiphilic stimuli-responsive azobenzene-aminoglycoside (a small molecule) conjugate, Azo-AG 5, and characterized it by UV and FTIR. Light responsive nature of Azo-AG 5 was assessed under UV-vis light. Self- assembly of Azo-AG 5 in aqueous solutions into nanostructures and their ability to act as drug(More)
In the recent studies, it has been demonstrated that incorporation of unnatural amino acid, α,β-dehydrophenylalanine, in small peptides results in stable self-assembled nanostructures with different sizes and shapes. Here, we have replaced the natural amino acid, phenylalanine, from our earlier reported work on self-assembled peptide, Boc-Pro-Phe-Gly-OMe,(More)
Self-assembled nanoformulations have been finding various applications in biomedical sciences. Here, we have designed and synthesized a small molecule based amphiphilic conjugate of azobenzene, Azo-PEG-OMe, which self-assembles into nanostructures in an aqueous environment. The formation of nanostructures was evidenced by light scattering and electron(More)
