Its specific targeting by natural or synthetic antibodies like molecularly imprinted polymers (MIPs), is therefore of interest. NUPR1 is an intrinsically disordered protein (IDP), such that it displays a high degree of flexibility and an unstable secondary/tertiary structure, resulting in a continuous fluctuation of its conformation in the free state. These characteristics are not in favor of the creation of homogeneous binding sites during molecular imprinting, so that imprinting using peptide epitopes is investigated. Based on an <i>in silico</i> rational approach, two α-helices from the model structure of NUPR1, as predicted by AlPhaFold, are selected. Two cysteine residues are added at both ends of the epitopes to form a disulfide bond, which provides high stability to the α-helix. The template peptides possess the same 3D structure as the epitope fragments in NUPR1. Consequently, they are effective in producing MIP nanogels that cross-react with high affinity (IC<sub>50</sub> 1 n<span>m</span>) only with NUPR1. The work indicates that α-helices, besides the preferred flexible loops, can be considered as viable template epitopes for MIPs, opening new opportunities for the obtention of selective antipeptide MIP nanogels for IDPs.</p>","PeriodicalId":18103,"journal":{"name":"Macromolecular bioscience","volume":"25 9","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the existing photosensitizers predominantly function as type II ROS generators. When ROS are present in excess, they are always wasted due to their short half-lives, which limit their ability to travel significant distances and effectively achieve therapeutic outcomes. In this study, the biological function of a single-component molecule, PdHF, is investigated. This molecule is formed by covalently conjugating 3-hydroxyflavone (3-HF) to a palladium(II) tetraphenyltetrabenzoporphyrin (PdTPTBP) photosensitizer. Subsequently, PdHF is loaded into the 2-hexamethyleneimino ethyl methacrylate (C7A)-modified PEG-<i>b</i>-PCL block copolymer (PC7A) to form a PdHF@PC7A micellar system capable of co-releasing CO and ROS under red-light irradiation. CO/ROS co-release can be attributed to the generation of singlet oxygen species that not only oxidize 3-HF to release CO but are concurrently reduced by the tertiary amine, C7A, to form cytotoxic superoxide anions and hydrogen peroxide.

Currently, the crosslinking process of bioinks presents challenges in control, resulting in diminished stability and reliability of the gel and the presence of residual crosslinking agents that may adversely affect cell viability within the gel. This study utilizes sodium alginate as the printing ink and calcium chloride as the crosslinking agent, employing a dual-mode 3D bioprinter for alternating printing. A crosslinking agent is injected through a solenoid valve after using an extrusion-based printing method to create multilayer cell scaffolds. By controlling the printing intervals and opening times of the valve, precise localized crosslinking is achieved, and multiple alternating prints can be performed according to the required thickness of the scaffold. The results indicate that this solenoid valve crosslinking technology significantly enhances the stability and biological properties of the scaffolds, including excellent hydrophilicity, decreased swelling rate, slow degradation rate, and improved mechanical properties. Additionally, due to the reduced residual crosslinking agent, the cell proliferation rate has significantly increased.
