pH-Responsive Molecular Tweezers

A Novel Composite Membrane for pH Responsive Permeation

Objective(s) In this study, a kind of pH sensitive composite membrane was prepared and drug permeation through it was investigated in terms of pH. Rationale of this study originated from the fact that a pH change which may be a result of a disease state in the body can trigger drug release. Materials and Methods  Here, a kind of pH sensitive composite membrane containing different nanoparticle ...

ph-responsive and macrophage evading low molecular weight chitosan coated nanoparticles for tumor-specific drug delivery

Controlling pH Responsive Polymersome Assembly

Vesicles are formed when a membrane curves to produce a spherical structure, which in turn entraps an aqueous volume within its lumen. When these structures are formed using a polymers, a polymeric vesicle or “Polymersome” is formed. The biomimetic nature of these assemblies has attracted much attention in the field of biomedicine over the last decade, especially with regards to therapeutic or ...

DNA hybridization catalysts and molecular tweezers

We demonstrate new methods for the control of DNA hybridiza tion formation of a loop with a protective strand is used to inhibit hybridiza tion and a DNA catalyst that opens the loop is used to catalyse hybridization A combination of inhibition and catalysis will allow control of the bonds formed between elements of a self assembled structure We also demonstrate a new class of nanomachine made ...
