“…We prepared two DTPA-bisamides that can react with styrene via chain transfer reactions via hydrogen abstraction from the benzylic carbon of the DPTA-bisbenzylamide (DTPA-BAm 2 ) or the allylic carbon , of DTPA-bisallyamine (DTPA-ALAm 2 ). The results were compared with those obtained in the co-polymerization with DPTA-bis-4-vinylbenzylamide (DTPA-VBAm 2 ), where the 4-vinylphenyl group would be expected to have a reactivity similar to that of styrene. − The resulting products were characterized by 1 H NMR to confirm their structures.…”

Mass cytometry (MC) is an emerging analytical technique in which an inductively coupled plasma time-of-flight mass spectrometer is employed to analyze the signals of isotopic labels on cell and microbead samples. Bead-based applications in mass cytometry require one to label the microbeads with various metal ions that can be individually identified by MC. This paper describes a novel approach to encoding microbeads with controlled levels of metal ions by introducing polymerizable metal complexes of the structure M(DTPA-VBAm2) in two-stage dispersion polymerization reactions. Using this method, the incorporation of various metal ions is effective and consistent in the investigated concentration range. As a result, this method provides a convenient path for synthesizing microbeads with controlled metal content for mass cytometry applications. As a proof-of-concept experiment, a sample of europium-labeled microbeads was surface-functionalized with a goat anti-mouse IgG antibody and tested by mass cytometry for its ability to detect a Lu-labeled mouse IgG. Surface functionalization involved a thin silica shell to which neutravidin was covalently attached. This experiment demonstrates the potential use of these microbeads as classifier beads for bead-based assays in MC.

Polymeric surfactants are a special class of the polymers that have amphiphilic characteristics of surfactants. In selective solvents, polymeric surfactants exhibit interesting association processes and develop self‐assembled structures. Their capacity to create micellar aggregates with stimuli‐responsive behavior in aqueous solutions, enables the creation of smart materials for many applications. The only restrictions to the creation of polymeric surfactants with complicated structures using current synthetic methods are the researchers' interests and creativity. The chemical structure of the polymer and its aqueous solution characteristics (viscosity and surface tension) should be demonstrated as having a distinct and commonly accepted connection. Unavailability of systematic and updated review on these important molecules demands a comprehensive compilation and consistent discussion on key physical aspects, characterization, synthetic techniques, and their useful applications like enhanced recovery of oil, antimicrobial potential, water treatment, pharmaceutical, etc.

“…To properly control the BC architecture including molecular weight, molecular weight distribution, functionality, and composition, it is necessary to employ controlled/living radical polymerization (CRP) methods. − Reversible addition–fragmentation chain transfer (RAFT) polymerization is one of the systems developed for CRP to produce a well-defined block copolymer. RAFT polymerization offers several advantages over other CRP techniques in terms of tolerance of impurities, reaction condition, and application to a broad range of vinyl monomers. − …”

A new series of hybrid triblock copolymers (TBCs) based on hard−soft−hard segments are synthesized by reversible addition−fragmentation chain transfer (RAFT) polymerization using a macroinitiator poly(ethylene glycol) (PEG) macromolecular chain transfer agent (macro-CTA) and monomer p-dodecylphenyl-N-acrylamide (DOPAM). The resulting TBCs are characterized and evaluated by 1 H NMR, gel permeation chromatography, and differential scanning calorimetry. Kinetic studies on triblock copolymerization indicated the controlled/living characteristic of RAFT polymerization with good distribution of molecular weight (M w /M n ≤ 1.39). All TBCs exhibited two melting temperatures (T m ) at 50 and 240 °C unlike PEG macro-CTA, which revealed a single T m at 50 °C. However, TBC-4 and TBC-5 showed strong T m (PDOPAM) peaks compared to TBC-1, TBC-2, and TBC-3, mainly due to the increase in the volume fraction of PDOPAM. Morphologies of TBCs are studied by atomic force microscopy and grazing incidence small-angle X-ray scattering. TBCs (TBC-2, TBC-4, and TBC-5) with different blocks ratios (f PDOPAM ≠ f PEG ) formed cylindrical phases, in particular TBC-5 containing a higher PDOPAM ratio (72%) generated a highly ordered cylindrical nanostructure. Contrastingly, TBC-3 with nearly the same length of PDOPAM (49%) and PEG (51%) self-assembled into the lamellar phase.
