Biomimetic biomineralization nanoplatform-mediated differentiation therapy and phototherapy for cancer stem cell inhibition and antitumor immunity activation

open access: yesAsian Journal of Pharmaceutical Sciences, 2023
Growing evidence suggests that the presence of cancer stem cells (CSCs) is a major challenge in current tumor treatments, especially the transition from non-CSCs to differentiation of CSCs for evading conventional therapies and driving metastasis.

Near-Infrared-Emitting Hemicyanines and Their Photodynamic Killing of Cancer Cells [PDF]

open access: yes, 2021
A series of hemicyanine dyes was synthesized starting from the vinyl chloride-based cyanine dye IR-780. The dyes absorbed and emitted in the near-infrared region, while heavy atom (bromo and iodo) substitution promoted the generation of both singlet ...

Tunable visible comb using Raman self-frequency shift, intermodal phase matching and cascading of nonlinearities in an all-fiber platform

open access: yesPhysical Review Research, 2023
Up-conversion of IR frequency combs from compact erbium fiber mode-locked lasers (MLLs) around 1550 nm is enabling the development of small-footprint visible combs for ultralow-power spectroscopy and quantum optics. Limited tunability of the IR MLLs, due

Recent progress in mitochondria-targeted drug and drug-free agents for cancer therapy [PDF]

open access: yes, 2019
The mitochondrion is a dynamic eukaryotic organelle that controls lethal and vital functions of the cell. Being a critical center of metabolic activities and involved in many diseases, mitochondria have been attracting attention as a potential target for

In vivo super-resolution photoacoustic computed tomography by localization of single dyed droplets [PDF]

open access: yes, 2020
The spatial resolution of photoacoustic (PA) computed tomography (PACT) is limited by acoustic diffraction. Here, we report in vivo superresolution PACT, which breaks the acoustic diffraction limit by localizing the centers of single dyed droplets.

Reduced erbium-doped ceria nanoparticles: one nano-host applicable for simultaneous optical down- and up-conversions [PDF]

open access: yes, 2014
This paper introduces a new synthesis procedure to form erbium-doped ceria nanoparticles (EDC NPs) that can act as an optical medium for both up-conversion and down-conversion in the same time.

Immunogenic Cell Death Photothermally Mediated by Erythrocyte Membrane-Coated Magnetofluorescent Nanocarriers Improves Survival in Sarcoma Model

open access: yesPharmaceutics, 2023
Inducing immunogenic cell death (ICD) during cancer therapy is a major challenge that might significantly improve patient survival. The purpose of this study was to develop a theranostic nanocarrier, capable both of conveying a cytotoxic thermal dose ...

Optimization of Near-Infrared Fluorescence Voltage-Sensitive Dye Imaging for Neuronal Activity Monitoring in the Rodent Brain

open access: yesFrontiers in Neuroscience, 2021
Many currently employed clinical brain functional imaging technologies rely on indirect measures of activity such as hemodynamics resulting in low temporal and spatial resolutions.

Photoactivatable Heptamethine-Based Carbonic Anhydrase Inhibitors Leading to New Anti-Antibacterial Agents [PDF]

open access: yes, 2023
With the aim to propose innovative antimicrobial agents able to not only selectively inhibit bacterial carbonic anhydrases (CAs) but also to be photoactivated by specific wavelengths, new heptamethine-based compounds decorated with a sulfonamide moiety ...
