CuBr2/EDTA-mediated ATRP for ultrasensitive fluorescence detection of lung cancer DNA

Journal of Advanced Research, 2020
In this paper, we reported a system for the ultrasensitive fluorescence detection of cytokeratin fragment antigen 21–1 DNA (CYFRA21-1 DNA) for the early diagnosis of lung cancer.

Electrochemical Investigation of Iron-Catalyzed Atom Transfer Radical Polymerization

Molecules, 2022
Use of iron-based catalysts in atom transfer radical polymerization (ATRP) is very interesting because of the abundance of the metal and its biocompatibility. Although the mechanism of action is not well understood yet, iron halide salts are usually used

Efficient Synthesis of Narrowly Dispersed Brush Copolymers and Study of Their Assemblies: The Importance of Side Chain Arrangement [PDF]

, 2009
Efficient, one-pot preparation of synthetically challenging, high molecular weight (MW), narrowly dispersed brush block copolymers and random copolymers in high conversions was achieved by ring-opening metathesis (co)polymerization (ROMP) of various ...

Macromolecular Engineering by Applying Concurrent Reactions with ATRP [PDF]

Polymers, 2020
Modern polymeric material design often involves precise tailoring of molecular/supramolecular structures which is also called macromolecular engineering. The available tools for molecular structure tailoring are controlled/living polymerization methods, click chemistry, supramolecular polymerization, self-assembly, among others.

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

Advanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design

Advanced Materials Technologies, EarlyView.
This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Crossing the Blood–Brain Barrier with Molecularly Imprinted Polymeric Nanocarriers: An Emerging Frontier in Brain Disease Therapy

Advanced Science, EarlyView.
Molecularly imprinted polymeric nanocarriers (nanoMIPs) offer robust, antibody‐mimetic platforms to overcome the blood‐brain barrier. The article surveys nanoMIP design and ligand‐directed surface engineering that harness receptor‐mediated transcytosis, and highlights therapeutic and diagnostic applications in neurodegeneration, brain tumors and ...

ATRP Synthesis of Sunflower Polymers Using Cyclic Multimacroinitiators [PDF]

ACS Macro Letters, 2015
Polymers with advanced architectures can now be readily and reproducibly synthesized using controlled living polymerization. These materials are attractive as potential drug carriers due to their tunable size, versatile methods of drug incorporation and release, and ease of functionalization with targeting ligands.

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication

Chemistry – A European Journal, EarlyView.
This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.
