Summary: The normal operation of lysosome, mitochondria, Golgi apparatus, and endoplasmic reticulum is crucial for maintaining cell homeostasis. A new NIR pH-dependent fluorescent probe, DCIC, was synthesized using the TICT mechanism to identify the viscosity of lysosomes. DCIC exhibited high sensitivity to viscosity in viscous media, with fluorescence intensity increasing by 180 times as viscosity increased from 1.0 cp to 438.4 cp. Moreover, DCIC showed a high localization ability for lysosome, mitochondria, Golgi apparatus, and endoplasmic reticulum, and could monitor lysosomal viscosity fluctuations using laser confocal microscopy.

Summary: Endogenous activated nanomedicines have significant potential in cancer therapy by improving therapeutic efficacy and reducing side effects. In this study, a novel nanomedicine (CuHCF) was developed based on a mixed-metal Prussian blue analogue, which could respond to endogenous labile iron pool achieving enhanced chemodynamic therapy and in situ NIR-II photothermal therapy of the tumor. The CuHCF showed low Fenton catalytic activity but significantly amplified reactive oxidative species generation when exposed to over-expressed Fe2+ in the tumor region via redox cycles. Furthermore, CuHCF exhibited enhanced near-infrared absorption and enabled in situ hyperthermia under NIR-II irradiation. Synergistic therapy of CDT/PTT was achieved by combining CuHCF with the ferroptosis inducer erastin.

In normal tissues, the AFD NPs remain in an off state due to FRET between Ag2S QDs and DBZ Pdots. However, the NIR-II fluorescence signal of AFD NPs can be rapidly turned on in tumor tissues by the overexpressed GSH, achieving a superior tumor-to-normal tissue (T/NT) signal ratio. The AFD NPs also provide NIR-II photothermal therapy (PTT) and chemodynamic therapy (CDT) for cancer treatment.

Summary: Nanomedicines have shown promise in cancer therapy due to their increased safety and efficiency compared to small-molecule drugs. However, the dense extracellular matrix (ECM) in tumors often hinders the accumulation and diffusion of nanoparticles, reducing their anticancer efficacy. To overcome this, strategies such as degrading ECM components and inhibiting ECM formation have been employed to enhance the therapeutic effects of nanomedicines. By degrading ECM components or inhibiting ECM formation, the accumulation and diffusion of nanoparticles in tumors can be improved, leading to enhanced chemotherapy and phototherapy. Additionally, ECM degradation can enhance the infiltration of immune cells into tumor tissues, resulting in a stronger immune response against tumors.

Summary: The authors developed ultrasmall TQFP-10 NPs with bright NIR-II fluorescence, prolonged blood circulation, and enhanced tumor accumulation for efficient orthotopic GBM imaging. Compared to traditional NPs, TQFP-10 NPs exhibited higher NIR-II fluorescence quantum yield and longer blood circulation half-life, leading to significantly improved tumor-to-normal tissue ratio in GBM imaging.

Summary: This study combined metal, polymer, and lipid nanoparticles to achieve enhanced therapeutic effects for cancer treatment using photothermal and photodynamic therapies, with improved cellular uptake by cancer cells and selective targeting of mitochondria through the mediation of triphenylphosphonium (TPP). The nanoparticles were found to accumulate predominantly in tumors in tumor-bearing mice, showing great improvement in efficacy compared to individual therapies.

Summary: This study introduces a new set of supramolecular nanotools for the generation and modulation of noncovalent/covalent pentacene dimer singlet fission (SF), which can convert to triplet pairs and individual triplets even under high dilution conditions. The encapsulated pentacene dimers exhibit high quantum yields and the yield of individual triplets is enhanced upon encapsulation. The SF features of both types of pentacene dimers can be readily tuned by changing the polyaromatic panels of the capsule.

Summary: Immunotherapy shows promise for tumor treatment, but its clinical effect is limited by tumor immunogenicity and the immunosuppressive microenvironment. Researchers combined metal-organic framework MIL-100 loaded with mitoxantrone (MTO) with photothermal-chemotherapy to enhance immunogenic cell death. The resulting MMH NPs, with dual therapeutic properties and imaging modes, showed high antitumor efficacy and immune effect when co-injected with anti-OX40 antibody in colorectal cancer. This novel combined therapeutic strategy is promising for future tumor therapy.

Summary: Through a localized coupling model, it has been demonstrated that the formation of a bright S-1 state in H-aggregate is due to the coupling between the low-lying intermolecular charge-transfer state and the upper bright Frenkel exciton, with the condition that the electron and hole transfer integrals are notably larger than the excitonic coupling. This theoretical finding not only explains recent experimental results but also provides insight into the compatibility between strong luminescence and high charge mobilities, which is important for OLETs and electrically pumped lasing.

Summary: Photoacoustic imaging (PAI) is a promising emerging imaging modality that enables spatially resolved imaging of optical tissue properties. However, extracting relevant tissue parameters from raw data is difficult, leading to the application of deep learning methods in PAI. These methods have advantages like fast computation times and adaptability to various problems, facilitating clinical translation.

Summary: The synergistic effect of photodynamic therapy (PDT) and photothermal therapy (PTT) shows superior clinical application prospects compared to single PDT or PTT. By designing and synthesizing a near-infrared (NIR) small molecule (ETTC), multiple functions such as NIR-II fluorescence imaging, photoacoustic imaging, PTT, and PDT were successfully achieved and optimized. This work provides a novel perspective for the development of efficient and versatile biomedical applications in a single molecule.

Summary: A NIR (NIR-I) probe with intrinsic multifunctionality was synthesized and encapsulated in an amphiphilic polypeptide to create polymeric micelles serving as a nanotheranostic platform for NIR-II imaging-guided photothermal therapy (PTT) and photodynamic therapy (PDT). In vivo studies demonstrated the real-time monitoring of P@BDP accumulation in tumors and the highly effective synergistic phototherapy under NIR-II imaging-guided PTT/PDT combination therapy.
