objective: bleaching of the teeth is considered as a safe, effective, and conservative procedure to treat discolored teeth. the aim of the present study was to compare the amount of mercury and silver released from amalgam after applying two brands of carbamide peroxide 16% bleaching gel. materials and methods: for this experimental study, 384 amalgam tablets were prepared. the samples were kep...

Here we report a coumarin based hydrogelator that can form bulk gels, or homogeneous thin gels via an electrochemical pH drop. The gel can then be strengthened by post-gelation photodimerisation of the coumarin groups by irradiating with UV light.

Aluminium zirconium tetrachlorohydrex glycine (AZG) is a popular antiperspirant/deodorant agent, formulated in various forms including the clear gels. Silicones are used for the preparation of these gels, giving them desirable characteristics. The aim of this study was to investigate the influence of various silicones, when used in combination, on the rheological properties of the resulting AZG...

Introduction Stimuli-responsive gels undergo abrupt changes in volume in response to environmental changes such as pH and temperature. Stimuli-responsive gels have attracted considerable attention as smart materials in the biochemical and biomedical fields, since they can sense environmental changes and induce structural changes by themselves. The fascinating properties of such stimuli-responsi...

Introduction The purpose of the current study was to determine optical sensitivity of N-isopropyl acrylamide NIPAM and polyacrylamide gelatin and tetrakis hydroxymethyl phosphoniun chloride (PAGAT) polymer gels for different wavelength of visible light spectrum applied in optical computed tomography method. Materials and Methods NIPAM and PAGAT polymer gels with conventional formulations used f...

Supramolecular chemistry has garnered important interest in recent years toward improving therapeutic efficacy via drug delivery approaches. Although self-assemblies have been deeply investigated, the design of novel drugs leveraging supramolecular is less known. In this contribution, we show that a Low Molecular Weight Gel (LMWG) can elicit cancer cell apoptosis. This biological effect results...
