Recent advances in metallopolymer-based drug delivery systems

Abstract

The recent (over the past five years) advances and problems associated with the use of metallopolymers as drug delivery systems (DDSs) are presented and assessed.

Electrospun nanofibers fromferrocene‐containingmultiblock copolymers prepared viaRAFTpolymerization withF127modified precursor

“…While the PFcMA 126 ‐F127‐PFcMA 126 nanofibers, it exhibits broad diffraction peaks at 2θ = 12.5°‐18.5° comparison to the polymer with many diffraction peaks at 2θ = 7.5°‐40°, showing the nanofibers is amorphous. Besides the orientation in electrospinning, crystallization is resulting from the phase separation of F127 block and backbone of the ferrocene‐containing side chain and eutectic of the chain fragment in multi‐block copolymer, 44–45,56 which is agreed with the DSC measurement.…”

Supramolecular photocatalysts fixed on the inside of the polypyrrole layer in dye sensitized molecular photocathodes: application to photocatalytic CO2 reduction coupled with water oxidation

“…28,29,[33][34][35] Functional polypyrrole lms containing metal complex units have been reported for various applications, e.g., catalytic reactions, sensors, and drug delivery. 28,29,[33][34][35][36][37][38][39][40][41] Deronzier et al reported that a system with a polypyrrole layer containing a Re(I) complex catalyst on Pt electrodes showed higher durability for electrocatalytic CO 2 reduction than the system with the corresponding mononuclear Re(I) complex in solution. 33,36,42 Morikawa et al deposited a polypyrrole layer containing a Ru(II) complex catalyst onto a p-type semiconductor photoelectrode, i.e., used a method of the rst type according to the abovementioned classication.…”

ROMP Synthesis of Side‐Chain Ferrocene‐Containing Polyelectrolyte and Its Redox‐Responsive Hydrogels Showing Dramatically Improved Swelling with β‐Cyclodextrin

“…The past decades witnessed the rapid development of ferrocenyl (Fc)‐containing polymers and their functional applications in various fields, [ 1–3 ] such as drug delivery, [ 4,5 ] magneto‐ceramics, [ 6 ] electro‐chromics, [ 7 ] hydrogels, [ 8–10 ] biomaterials, [ 11 ] sensors, [ 12,13 ] catalysis, [ 14 ] and stimuli‐responsive materials. [ 15 ] Especially, the elegant application of ring‐opening polymerization (ROP) of strained silicon‐bridged [ 1 ] ferrocenophane monomers led to a whole field of chemistry poly (ferrocenylsilanes) (PFS)‐based main‐chain Fc‐containing polymers.…”
