Expanding the Chemical Space of Cyclic Polyphthalaldehyde via Post‐Functionalization

Advanced Science, Volume 13, Issue 13, 3 March 2026.
In this work, we developed a post‐functionalization approach to achieve water‐soluble cyclic polyphthalaldehyde (cPPA) polymers via click chemistry. ABSTRACT Cyclic polyphthalaldehydes (cPPAs) are hydrophobic cyclic polymers with stimuli‐responsive depolymerization property. The introduction of hydrophilic functionalities to cPPAs is challenging due to

Comparison of Pre‐ and Postoperative Gut Microbiota Diversity in Patients With Rectal Cancer Undergoing Stoma Creation and Closure

Annals of Gastroenterological Surgery, Volume 10, Issue 2, Page 492-501, March 2026.
We investigated the impact of temporary stoma creation and closure on gut microbiota diversity in rectal cancer patients. 16S rRNA sequencing revealed that microbial diversity significantly decreased postoperatively in the stoma group but remained stable in non‐stoma patients.

Photo‐Catalyzed Labeling of Amyloid Deposits in Human Tissue to Proteotype Amyloidosis Diseases

Aggregate, Volume 7, Issue 3, March 2026.
Amyloid‐ID, a ThT‐like photocatalytic probe, enables proteotyping of amyloid deposits by ROS‐mediated protein labeling. Applied to patient biopsies, amyloid‐ID identifies potential fibrinogen‐derived amyloid in laryngeal amyloidosis, revealing a mechanically sensitive fibrillation mechanism linked to vocal cord friction.

Dimension and Valence Manipulation of Luminescent Manganese‐Based Perovskites via Alternating Cation Interactions

Aggregate, Volume 7, Issue 3, March 2026.
Through dimensional reduction of Mn2+‐based 3D perovskite (CsMnCl3·2H2O), we successfully constructed 2D@3D perovskites with superior photoluminescence (PL) performances. Alternating cation interactions (ACIs) effectively stabilized the 2D@3D perovskite via strengthened electrostatic interactions and extensive H‐bondings.

A targeted antiferromagnetic nanoprobe for ultra‐sensitive magnetic resonance imaging detection of sub‐millimeter esophageal tumors

BMEMat, Volume 4, Issue 1, March 2026.
We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐
