Folic acid-Conjugated pH/temperature/redox multi-stimuli responsive biodegradable polymer microspheres for delivery of anti-cancer drugs
The folic
acid (FA)-conjugated pH/temperature/redox multi-stimuli responsive poly(methacrylic
acid-co-N,N-bis(acryloyl)cystamine/poly(N-isopropylacrylamide -co-glycidyl methacrylate-co-N,N-bis(acryloyl)cystamine) microspheres
were prepared by a
two-stage distillation-precipitation polymerization
with subsequent surface modification with FA. The microspheres were
characterized by transmission ...

[Macromolecules] From Polymer Sequence Control to Protein Recognition: Synthesis, Self-Assembly and Lectin Binding
A novel, highly efficient methodology to synthesize gradient
glycopolymers has been successfully developed involving concurrent
enzymatic monomer transformation and reversible addition–fragmentation
chain transfer (RAFT) polymerization. By synchronizing enzymatic monomer
transformation with polymerization, a continuous supply of the second
monomer (glycomonomer) is achieved during the...

[Chem. Comm.] Visible light induced fast synthesis of protein-polymer conjugates: controllable polymerization and protein activity
Herein visible
light is used to induce RAFT polymerization from protein for preparing
protein-polymer conjugates at ambient temperature. Polymerization is
fast and can be conveniently controlled with irradiation time. By
site-specific polymerization of NIPAm to protein, the protein activity
is maintained and in certain cases it presents an efficient
on-off-switchable property.

Tough Biomimetic Hydrogels with High Fatigue Resistance Based on Self-Assembled Conjugated Polymer Belt Mesh Interlaced with a Polyelectrolyte Network
Supertough biomimetic hydrogels have been fabricated through in
situ synthesis and guided assembling of positively charged conjugated polymer belts
by using a parent poly(2-acrylamido-2-methylpropanesulfonic acid)/poly-
(acrylamide) double network (PAMPS/PAAm DN) gel template. The interpenetrating
structures of the poly(3,4-ethylenedioxythiophene) (PEDOT) belt
mesh and PAMPS/PAAm host network have...

[RSC Advances] Polymer brushes functionalized Janus graphene oxide/chitosan hybrid membranes
A robust and simple method is reported to prepare polymer brushes functionalized Janus graphene oxide (GO)/chitosan hybrid membranes via the combination of interface self-assembly of GO and chitosan, with subsequent self-initiated photografting and photopolymerization (SIPGP) from both sides of GO/chitosan composite membranes.

[Chem. Eur. J.] Chemoselective Phototransformation of C-H Bond on Polymer Surface via a Novel Photoinduced Cerium Recycling Redox
It is
generally accepted that Ce4+ is unable to directly oxidize inert
alkyl C-H bond without the assistance of adjacent polar groups. Herein we
demonstrated in our newly developed confined photochemical reaction system,
this recognition might be challenged. As we found, when a thin layer of CeCl3/HCl
aqueous solution was applied onto polymeric substrate, and under UV
irradiation, Ce3+ was firstly...

[Langmuir] Controlled evaporative self-assembly of polyacrylic acid in a confined geometry for fabricating pattern ed polymer brushes
A simple yet robust approach was exploited to fabricate large-scaled patterned polymer brushes by combining controlled evaporative self-assembly (CESA) in a confined geometry and self-initiated photografting and photo polymerization (SIPGP). Our method was carried out without any sophisticated instruments with lithograpy free, overcoming current difficulties in fabricating polymer patterns by us...

[Chem Commun] Microcontact Printing Graphene Oxide Nanosheet for Fabricating Patterned Polymer Brushes
A robust strategy is developed to fabricate micro-patterned graphene oxide (GO) films on the hydroxylated surface via micro-contact printing induced supramolecular self-assemble of multiple hydrogen-bond formation between GO nanosheet and silicon substrate. Existing photo active sites on the surface of GO allows the further amplification of GO in chemical functions to grow polymer brushes via self...
