Summary: By grafting SBMA zwitterionic monomers onto PES membranes using corona-induced graft co-polymerization, the water-oil flux was significantly enhanced (over 1100%) without affecting oil rejection. The stability of the modified membranes over a long period was confirmed through a 10% reduction in flux after immersing in deionized water for 30 days. This study demonstrates the potential for practical applications in industrial settings.

Summary: A double-network hydrogel was prepared by embedding an initiator (HHy-Br) and reinforcing with Fe3+, followed by grafting the antifouling polymer (PSBVI) onto the HHy-Br substrate via subsurface-initiated atom transfer radical polymerization (sSIATRP) to obtain HHy-PSBVI. Fe3+ increased the crosslinking density of HHy-Br, resulting in improved tensile strength and anti-swelling properties of the hydrogel. The presence of Fe3+ also promoted the sSIATRP process. HHy-PSBVI exhibited decreased friction coefficient and excellent antibacterial and antifouling properties due to the hydration of the zwitterionic polymer and the bactericidal effect of the cationic imidazole group.

Summary: This study demonstrates two different routes to synthesize polymer-dendrimer hybrids with advantageous self-assembly properties onto silicon oxide surfaces. The first route yields network-like structures with crosslinked PLL and ZIDs, while a more defined linear PLL-ZID macromolecule is formed through a controlled CuAAC click reaction. The potential use of these hybrids as antifouling coatings and for selective detection of target analytes is confirmed through various testing methods.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: Marine biological pollution is a global challenge in marine engineering. MXene nanosheets and zwitterionic polymers have been investigated as effective materials for marine anti-biofouling. In this study, MXene-PDA was prepared by self-assembling polydopamine layer on the MXene nanosheets, followed by introducing the zwitterionic polymer PEIS through a Michael addition reaction to obtain MXene-PEIS. The resulting MXene-PEIS exhibited excellent antifouling performance through the cooperative antifouling effect of MXene nanosheets and PEIS (88% improved antibacterial rate and 98% decrease in microalgae adhesion density). Furthermore, the nanocomposite antifouling coatings (MXene-PEIS/SP) showed good antifouling performance due to the synergy among MXene, PEIS, and self-polishing coatings.

Summary: L-Dopa is an effective therapy for Parkinson's disease, but its short half-life and narrow therapeutic window may lead to side effects. Monitoring the concentration of L-Dopa using wearable biosensors is significant to reduce complications. However, the high concentration of interferents in the body poses challenges. A minimal-invasive L-Dopa biosensor based on a flexible differential microneedle array (FDMA) is proposed to address this. The sensor exhibits excellent anti-interference performance and accuracy.

Summary: Chemotherapy is the main method of treating malignant tumors, but commonly used drugs have high toxicity, poor solubility, low targeting ability, and high side effects. In this study, zwitterionic micelles assembled by modified amphiphilic dendrimers showed great stability and controlled drug release. Moreover, these micelles had higher cellular uptake rates and cytotoxicity, resulting in better tumor inhibition compared to free drugs. Therefore, the prepared targeting nanodrug has great potential for antitumor therapy.

Summary: The synthesis of biocompatible and efficient polymeric micelles for drug delivery has attracted much attention. In this study, amphiphilic molecules (PMPC) were synthesized using zwitterionic linear polyethyleneimine (PEI) as the hydrophilic segment and mercapto-paclitaxel as the hydrophobic segment. Chemotherapeutic doxorubicin (DOX) was encapsulated in the PMPC micelles to prepare DOX-loaded micelles (PMPC-DOX micelles) through self-assembly. The results showed that the PMPC-DOX micelles exhibited good stability in protein solution and released DOX at a rate of 48.12% within 36 h at pH 5.5. Furthermore, the PMPC-DOX micelles demonstrated superior tumor targeting ability and antitumor effect compared to free DOX, with a tumor inhibition rate of 89.7% after 14 days of treatment. The PEI-based drug-loaded micelles provide a new approach for nanodrug delivery system design.
