Tunable drug loading and release from polypeptide multilayer nanofilms
Polypeptide multilayer nanofilms were prepared using electrostatic layer-by-layer self-assembly nanotechnology. Small charged drug molecules (eg, cefazolin, gentamicin, and methylene blue) were loaded in polypeptide multilayer nanofilms. Their loading and release were found to be pH-dependent and could also be controlled by changing the number of film layers and drug incubation time, and applyi...
متن کاملAdvances in polyelectrolyte multilayer nanofilms as tunable drug delivery systems.
There has been considerable interest in polyelectrolyte multilayer nanofilms, which have a variety of applications ranging from optical and electrochemical materials to biomedical devices. Polyelectrolyte multilayer nanofilms are constructed from aqueous solutions using electrostatic layer-by-layer self-assembly of oppositely-charged polyelectrolytes on a solid substrate. Multifunctional polyel...
متن کاملControl of stability of polypeptide multilayer nanofilms by quantitative control of disulfide bond formation
The crosslinking of polymers in a polymeric material will alter the mechanical properties of the material. Control over the mechanical properties of polyelectrolyte multilayer films (PEMs) could be useful for applications of the technology in medicine and other areas. Disulfide bonds are ‘natural’ polypeptide crosslinks found widely in wild-type proteins. Here, we have designed and synthesized ...
متن کاملpH-controlled drug loading and release from biodegradable microcapsules.
Microcapsules made of biopolymers are of both scientific and technological interest and have many potential applications in medicine, including their use as controlled drug delivery devices. The present study makes use of the electrostatic interaction between polycations and polyanions to form a multilayered microcapsule shell and also to control the loading and release of charged drug molecule...

Introduction: Acne is a disorder of the pilosebaceous unit of the skin and can present as non inflammatory and or inflammatory lesions. Tretinoin has been used therapeutically for over three decades. It is best known for its comedolytic effects on acne. It also inhibits comedone rupture, thus decreasing inflammatory events. Tretinoin is available in 0.01% to 0.1% as cream, gel or lotion. The ...
