AbstractThe major challenge faced by the pharmaceutical industry is the aggregation of drug nanoparticles. Controlling the surface forces between the particles with the help of surfactants and polymers may overcome this problem. An attempt has been made to develop nanocrystals of the telmisartan to improve its solubility by applying an anti-solvent...

Chitosans, a family of ß-(1,4)-linked, partially N-acetylated polyglucosamines, are considered to be among the most versatile and most promising functional biopolymers. Chemical analysis and bioactivity studies revealed that the functionalities of chitosans strongly depend on the polymers’ degree of polymerization and fraction of acetylation. More ...

BackgroundSuture materials and techniques are frequently evaluated in ex vivo studies by comparing tensile strengths. However, the direct measurement techniques to obtain the tensile forces in canine skin are not available, and, therefore, the conditions suture lines undergo is unknown. A soft elastomeric capacitor is used to monitor deformation in...

Room temperature phosphorescence (RTP) has drawn increasing attention for its great potential in practical applications. Polymers with large molecular weights and long chains tend to form coil, which can endow them with a high degree of possible rigidity and result in the much restricted non-radiative transition. Also, the intertwined structure of ...

© 2019 American Chemical Society. The efficiency of nanoparticle-based drug delivery systems to accumulate in targeted tumor sites is low owing primarily to the various biological mechanisms that promote premature clearance, such as renal filtration or the mononuclear phagocyte system (MPS). Such obstacles to enhanced tumor accumulation of nanomedi...

The research community is intent on harnessing increasingly complex biological building blocks. At present, cells represent a highly functional component for integration into higher order systems. In this review, we discuss the current application space for cellular coating technologies and emphasize the relationship between the target application ...

Copyright © 2018 American Chemical Society. Glycopolymer-coated nanoparticles have attracted significant interest over the past few years, because of their selective interaction with carbohydrate receptors found on the surface of cells. While the type of carbohydrate determines the strength of the ligand-receptor interaction, the presentation of th...

Poly (o-aminophenol-co-m-phenylenediamine) P(oAP-mPDA) as a copolymer is successfully synthesized by mechanochemical solid state polymerization (MCSSP) as a green and simple method. The mechanochemical solid state polymerization is achieved by a developed Mortar Grinder RM200 without using any solvents during the preparation process. The copolymer ...

Poly(methyl methacrylate) (PMMA) and poly(α-methyl styrene-co-acrylonitrile) (PαMSAN) form partially miscible blends with lower critical solution temperature (LCST) behaviour. We revisit this system using small angle neutron scattering (SANS), examining the effect of molecular weight (Mw) of deuterated PMMA (dPMMA), blend composition (φ) and temper...

We report on a simple chemical etching method that enables nonlinear tapering of Polymer Optical Fiber (POF) tips to manufacture Compound Parabolic Concentrator (CPC) fiber tips. We show that, counter-intuitively, nonlinear tapering can be achieved by first etching the core and not the cladding. The etching mechanism is modelled and etched tips are...
