Abstract Protein function results from the precise folding of polypeptides into bespoke architectures. Taking inspiration nature, field single‐chain nanoparticles (SCNPs), intramolecularly crosslinked synthetic polymers, emerged. In contrast to SCNPs is generally defined by parent polymer or applied crosslinker, rather than crosslinking process itself. This work explores cyanopyridine–aminothiol click reaction crosslink peptide‐decorated polymers intra‐macromolecularly endow resulting with emerging functionality, conversion N‐terminal cysteine units pyridine‐thiazolines. Dimethylacrylamide based different cysteine‐terminated amino acid sequences tethered their sidechains are investigated ( P1 (C), P2 (GDHC), P3 (GDSC)) and SCNPs. Since deprotection yields disulfide‐based SCNPs, a direct comparison between disulfide pyridine‐thiazolines possible. revealed two properties pyridine‐thiazoline SCNPs: 1) The formation gave rise metal binding sites within SCNP, which complexed iron. 2) Depending on peptide sequence in precursor polymer, hydrolytic activity either increased (GDHC) decreased (GDSC) upon compared identical crosslinks.

In this work, a photoelectrochemical (PEC) sensor for ovarian cancer detection was constructed based on TiO2/poly(5-formylindole) (P5FIn)heterojunction using cascade amplification. The combined of multiple markers instead single mode can improve diagnostic accuracy. photoelectron conversion efficiency and photocurrent response were significantly improved by the reaction detector glutathione (GSH) with cystine. 17β-Estradiol (E2) had negative effect PEC response, reducing signal, ultimately realizing sensitive GSH E2. good performance E2, linear range (LDR) 0.5–1000 μM, limits (LOD) 0.167 μM 0.1224 pM, respectively, 0.0003671–36.71 nM.

Abstract In the last decade, messenger ribonucleic acid (mRNA)-based drugs have gained great interest in both immunotherapy and non-immunogenic applications. This surge can be largely attributed to demonstration of distinct advantages offered by various mRNA molecules, alongside rapid advancements nucleic delivery systems. It is noteworthy that immunogenicity presents a double-edged sword. context immunotherapy, extra supplementation adjuvant generally required for induction robust immune responses. Conversely, non-immunotherapeutic scenarios, activation unwanted considering host tolerability high expression demand mRNA-encoded functional proteins. Herein, mainly focused on linear non-replicating mRNA, we overview preclinical clinical progress prospects medicines encompassing vaccines other therapeutics. We also highlight importance focusing host-specific variations, including age, gender, pathological condition, concurrent medication individual patient, maximized efficacy safety upon administration. Furthermore, deliberate potential challenges may encounter realm disease treatment, current endeavors improvement, as well application future advancements. Overall, this review aims present comprehensive understanding mRNA-based therapies while illuminating prospective development drugs.

Incorporating d-amino acids into peptides can influence the intermolecular interactions of peptides, thus determining morphology and functionality self-assembled supramolecular structures. Based on this, we propose a modular chirality regulation strategy designed four chiral by adjusting different functional modules. The control coassembly nucleic virus-like vesicles with controlled diameters enzyme-responsiveness. Compared homochiral heterochiral inversion in their hydrophobic domain transformed more assemblies response to highly expressed enzyme matrix metalloproteinase 7 (MMP-7) cancer cells showed higher endosomal membrane disruption activity. Moreover, exhibit high efficiency selectivity delivering siRNA gene drugs inhibiting cell growth, achieving mortality rate 95% cells. These results provide promising for designing peptide-based acid delivery systems through modulation.

Nanotheranostics—where nanoscale materials serve both diagnostic and therapeutic functions—are rapidly transforming gene therapy by tackling critical delivery challenges. This review explores the design engineering of various nanoparticle systems (lipid-based, polymeric, inorganic, hybrid) to enhance stability, targeting, endosomal escape genetic payloads. We discuss how real-time imaging capabilities integrated into these platforms enable precise localization controlled release genes, improving treatment efficacy while reducing off-target effects. Key strategies overcome barriers (such as proton sponge effect photothermal disruption) achieve nuclear are highlighted, along with recent advances in stimuli-responsive that facilitate spatiotemporal control expression. Clinical trials preclinical studies demonstrate expanding role nanotheranostics managing cancer, inherited disorders, cardiovascular neurological diseases. further address regulatory manufacturing hurdles must be for widespread clinical adoption nanoparticle-based therapies. By synthesizing progress ongoing challenges, this underscores transformative potential effective, targeted, image-guided delivery.
