Cancer phototheranostics is a new mode of precise treatment based on fluorescent and photothermal imaging (PTI), combined with photodynamic (PDT) therapy (PTT). Herein, we designed photoactive Pt(IV) prodrug Pt-1 BODIPY-based triplet photosensitizer as an axial ligand that exhibits cytotoxic effects through both PDT photoactivated chemotherapy (PACT). Based the prodrug, developed multifunctional theranostic nanoplatform Pt-NPs PDT/PTT activity, capable light-induced cisplatin release suitable for tumor imaging. Upon 660 nm laser irradiation, efficiently causes regional hyperpyrexia, conversion efficiency 42.1%. Synergistically, acts type I agent. In vivo PTI studies have shown bright fluorescence CT-26 after intravenous injection Pt-NPs, indicating accumulation retention in tumor.

Nanothermometers can detect changes in the local temperature living cells and vivo, revealing fundamental biological properties. Despite exploration of different temperature-responsive materials, design development temperature-sensing probes with high brightness sensitivity remain a daunting challenge. Here, we employed UiO-66 type metal-organic frameworks (MOFs) to anchor UNCPs on surface MOFs for constructing MOF@UCNPs nanohybrids. The situ composite method leads coordination interaction between ligands UCNPs, enabling controlled formation UCNPs. Remarkably, favors anomalous thermo-enhanced luminescence, achieving 35-fold enhancement UiO-66@NaYF4:Yb/Tm at 413 K. Furthermore, these nanohybrids luminescence are developed as multifunctional bioimaging intracellular sensing, demonstrating thermal 1.92% K-1 physiological range. Based findings, monitoring position was successfully carried out by designed nanoprobes vivo. These findings underscore potential nanohybrids, opening up new avenues platform analysis.

Photodynamic therapy (PDT) offers minimally invasive and repeatable cancer treatment options. Despite advancements in photosensitizer (PS) design, the optical control of PS activation remains unexplored. Here, we present first photoswitchable based on a BOAHY-BODIPY dyad system. Inspired by BODIPY multimer structures BOAHY's photoisomerization properties, designed mono-(4 series) bis-BOAHY-BODIPY (5 conjugates. These dyads primarily generate reactive oxygen species via type-I process under white light. Notably, 4 series compounds demonstrated effective photocytotoxicity photoswitching properties vitro. Building these, iodinated monoconjugates to develop highly efficient PS, 6b, which exhibited enhanced intersystem crossing type-II generation due reduced singlet-triplet energy gap. As demonstration PDT agents, this strategy introduces new approach with significant potential for selective clinical applications.

Cell penetrating peptides (CPPs) are usually positive charged and have good cell membrane permeability. Meanwhile, CPPs facile to synthesize, can be functionalized satisfy different demands, such as cyclization, incorporating unnatural amino acids, lipid conjugation. These properties made them efficient drug-delivery tools deliver therapeutic molecules cells tissues in a nontoxic manner, including small molecules, DNA, siRNA, proteins other various nanoparticles. However, the poor serum stability low tumor targeting ability also hindered their broad application. Besides, inappropriate chemical modification lead disruption nonspecific toxicity. In this paper, we first reviewed recent advances CPP applications for cancer therapy via covalent or non-covalent manners. We carefully analyzed advantages disadvantages of each modifications drug delivery. Then, concluded progress clinical trials diseases. Finally, discussed challenges opportunities met translate into applications. This review presented new insight delivery, which could provide advice on design clinically effective systemic delivery systems using CPPs.

Abstract Type I photosensitization is of particular significance in the anaerobic tumor treatment. Nonetheless, development high‐performance type photosensitizers (PSs) remains challenging, due to weak absorption and inefficient intersystem crossing (ISC) progress. Herein, an effective approach toward a near‐infrared (NIR) PS ( NIR‐BN ) demonstrated using boron/nitrogen‐embedded polycyclic aromatic hydrocarbon with multiple‐resonance (MR) character, for first time. A small singlet‐triplet splitting (Δ E ST = 0.09 eV) high molar extinction coefficient (3.3 × 10 4 M −1 cm NIR MR‐configured supports efficient ISC triplet sensitization. The distorted molecular configurations induce multi‐model structural relaxations after optical excitation, resulting remarkable photothermal conversion efficiency exceeding 50% nanoparticles. Of note, nanoparticles are capable generating highly toxic superoxide anion radical (O 2 •− under 660 nm laser irradiation, benefiting from vigorous intramolecular dihedral angle vibrations excited states. Consequently, biocompatible demonstrates superior performance vivo synergistic photodynamic therapies.

These molecules specifically target integrin αvβ3 and form polysaccharide-structured nanofiber network on vascular surface. This protects cells without compromising their normal physiological functions. The constructed layer significantly increased xenograft by 1.64-fold compared untreated groups. work introduces novel enhance heart xenografts.
