Chitosan derivatives targeting lipid bilayers: Synthesis, biological activity and interaction with model membranes
(2017-01-01)
The antimicrobial activity of chitosan and derivatives to human and plant pathogens represents a high-valued prospective market. Presently, two low molecular weight derivatives, endowed with hydrophobic and cationic character ...
Chitosan derivatives targeting lipid bilayers: Synthesis, biological activity and interaction with model membranes

Effect of structure and bonding on the interfacial properties and the reactivity of layered double hydroxides and Zn hydroxide salts
(Elsevier Science, 2012-12)
Both layered double hydroxides (LDHs) and Zn layered hydroxide salts (LHSs) are intercalation compounds with potential applications as pollutant sorbents and antimicrobial, drug, and pesticide carriers, among others. Their ...
Modulation of Hydrophilic/Hydrophobic Character of Porous Environments in Metal-Organic Frameworks via Direct Polymer Capping Probed by NMR Diffusion Measurements
(American Chemical Society, 2019-08-01)
The ability to create extended porous networks, such as those composed of metal-organic frameworks (MOFs), with tailored hydrophilic/hydrophobic character is crucial for adapting such widely used supports to different ...
Hydrophilization of PVC surfaces by argon plasma immersion ion implantation
(Kluwer Academic/plenum Publ, 2003-03-01)
Commercial polyvinylchloride (PVC) sheets were treated by plasma immersion ion implantation, PIII. Samples were immersed in argon glow discharges and biased with 25 kV negative pulses. Exposure time to the bombardment ...
Morphological and Chemical Effects of Plasma Treatment with Oxygen (O-2) and Sulfur Hexafluoride (SF6) on Cellulose Surface
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2017-01-01)
Cellulose is a polymer widely available in nature, however its applications may be restrict due to its hydrophilic character. The creation of hierarchical structures on the surface is one of the required factors to obtain ...

Selectivity in the mechanism of action of antimicrobial mastoparan peptide Polybia-MP1
(Springer, 2008-07-01)
Many potent antimicrobial peptides also present hemolytic activity, an undesired collateral effect for the therapeutic application. Unlike other mastoparan peptides, Polybia-MP1 (IDWKKLLDAAKQIL), obtained from the venom ...
