Polymer-based nanomedicine is a large and fast growing field. systems have been extensively used as therapeutic carriers well bioimaging agents for example in tumour diagnosis. However, fewer polymeric able to combine both therapy imaging new field that called theranostics (theragnostics). This review aims summarise the recent developments trends on theranostics. Four different types of therapies/treatments are examined namely drug delivery, gene photodynamic hyperthermia treatment combined...
Ferrous core-shell nanoparticles consisting of a magnetic γ-Fe2O3 multi-nanoparticle core and an outer silica shell have been synthesized covalently functionalized with Rhodamine B (RhB) fluorescent molecules (γ-Fe2O3/SiO2/RhB NPs). The resulting γ-Fe2O3/SiO2/RhB NPs were integrated renewable naturally-abundant cellulose derivative (i.e. acetate, CA) that was processed in the form electrospun fibers to yield multifunctional fibrous nanocomposites. encapsulation within covalent anchoring RhB...
Reversible addition−fragmentation chain transfer (RAFT) polymerization was employed for the preparation of homopolymer and copolymer (co)networks based on four monomer units, belonging to three types: methacrylates, acrylates, styrenics. In particular, n-butyl methacrylate 2-(dimethylamino)ethyl (DMAEMA) (hydrophobic hydrophilic-ionizable monomers, respectively), acrylate (hydrophobic) styrene were used. Amphiphilic block conetworks prepared by RAFT via cross-linking linear triblock...
The stable free radical polymerization (SFRP) process based on (1,3-diphenyl-1,4-dihydro-1,2,4-benzotriazin-4-yl), the so-called 'Blatter radical', and several C-7 substituted derivatives is introduced for first time of styrene. Polystyrenes characterized by polydispersity indices in 1.05 − 1.27 range were obtained presence Blatter its containing CF3, Ph, Fur-2-yl 4-PhC6H4 substituents, while proceeded either a non-controlled manner or very low yields halogen (Cl, Br, I) substituents. This...
Ongoing research is actively exploring the use of immune checkpoint inhibitors to treat solid tumors by inhibiting PD-1/PD-L1 axis and reactivating function cytotoxic T effector cells. Many types tumors, however, are characterized a dense stiff stroma difficult treat. Mechanotherapeutics have formed recent class drugs that aim restore biomechanical abnormalities tumor microenvironment, related increased stiffness hypo-perfusion. Here, we developed polymeric formulation containing...
