In this study, an ion pair between polyethyleneimine and α-lipoic acid was employed as a reduction-responsive amphiphilic helper molecule and applied to stabilize DOPE liposomes. The ion pair exhibited UCST-type behavior, and its phase transition temperature decreased from approximately 42.6 °C to 37.7 °C, 29.6 °C, and 22.9 °C upon treatment with 5, 10, and 20 mM dithiothreitol, respectively. DOPE liposomes prepared using the ion pair enabled calcein encapsulation, and the DOPE: IP mass ratio of 10:1 showed the highest quenching efficiency of 48.1% together with a low polydispersity index of 0.105, indicating uniform liposome formation. Transmission electron microscopy further confirmed the formation of multilamellar structures in DOPE liposomes incorporating the ion pair. In release experiments, Lip-CHEMS (10:1) exhibited negligible release regardless of DTT, whereas Lip-IP (10:1) showed a stepwise increase in release with increasing DTT concentration, reaching approximately 12% at 20 mM DTT. Within the temperature range of 25–45 °C, temperature elevation alone did not produce a clear additional increase in release. These results show that the PEI/ALA ion pair is not merely an alternative to conventional DOPE helper molecules, but a functional helper molecule that simultaneously enables bilayer stabilization and reduction-triggered modulation of membrane permeability.

To address the issues of lengthy preparation times and suboptimal performance associated with conventional heating methods, this study proposes a novel microwave-assisted polymerization process for synthesizing poly(4-acetoxystyrene), the precursor of PHS, thereby achieving efficient synthesis of poly(4-acetoxystyrene). 4-Acetoxystyrene was used as the monomer, benzoyl peroxide (BPO) as the initiator, and toluene as the solvent.

Citric acid modification introduced functional sites, tuned cavity structure, and linked β-CD units into oligomer, overcoming native β-CD’s limitations to serve as an ideal hydrogel component. The incorporation of CA-β-CD into P(AA-co-AM) formed a porous network, enabled synergistic interactions, enhanced stability, and integrated CA-β-CD’s adsorption superiority with the polymer’s robust matrix.
