Nanoparticle Drug Delivery The encapsulation of nanoparticles in hydroxypropyl methyl cellulose is key to treat colorectal cancer through oral administration. In article 2202672 by Ilaria Rea, Hélder A. Santos, and co-workers, gelatin-coated diatomite loaded with galunisertib are functionalized an anti-L1-CAM antibody that targets metastatic colon cells. These then encapsulated a gastro-resista...
In this study, we have explored the slow (of the order of several hundreds of picoseconds) relaxation dynamics of water associated with the hydration shell of a biocompatible polymer, hydroxypropyl cellulose (HPC)-water mixture as a function of HPC concentration using time-resolved fluorescence spectroscopy. The relaxation dynamics slows down with a progressive increase in HPC content indicatin...
A series of 4alkyoxybenzoyloxypropyl cellulose (ABPC-n) samples was synthesized via the esterification of hydroxypropyl cellulose (HPC) with 4-alkoxybenzoic acid bearing different numbers of carbon atoms. The molecular structure of the ABPC-n was confirmed by Fourier transform infrared (FT-IR) spectroscopy and H NMR spectroscopy. The liquid crystalline (LC) phases and transitions behaviors were...
Porous polymer coatings are used to control drug release from pharmaceutical products. The coating covers a core and depending on the porous structure, different rates obtained. This work presents mass transport simulations performed ethyl cellulose films with porosities. were high spatial resolution 3D data obtained using focused ion beam scanning electron microscope. effective diffusion coeff...
BACKGROUND Derivatized celluloses, such as methylcellulose (MC) and hydroxypropyl methylcellulose (HPMC), are of pharmaceutical importance and extensively employed in tablet matrices. Each batch of derivatized cellulose is thoroughly characterized before utilized in tablet formulations as batch-to-batch differences can affect drug release. The substitution pattern of the derivatized cellulose p...
There is an urgent need to coat the surfaces of medical devices, including implants, with antimicrobial agents to reduce the risk of infection. A peptide array technology was modified to permit the screening of short peptides for antimicrobial activity while tethered to a surface. Cellulose-amino-hydroxypropyl ether (CAPE) linker chemistry was used to synthesize, on a cellulose support, peptide...
