Migration of Erucamide in Polyethylene Film

open access: yesPolymer Engineering &Science, EarlyView.
Erucamide migration in polyethylene films as a function of time and temperature, evaluated by FTIR‐PAS and correlated with changes in surface morphology and contact angle. ABSTRACT Erucamide is a migratory slip agent widely used in polyethylene (PE) films for flexible packaging applications, particularly those processed on high‐speed filling and ...

Intelligent Continuum Micromachines in Complex Confined Spaces

open access: yesSmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

open access: yesSmall, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

Miniaturization in Photoacoustic Tomography

open access: yesBiomedical Optics 2016, 2016
Several novel concepts of miniaturization in photoacoustic tomography (PAT) will be presented. These miniaturizations can drastically extend the utility of PAT to allow, for example, fabrication of a small endoscope, realization of compact microscopy, and functional imaging of freely moving animals.

Two‐Photon Endomicroscopy for Image‐Guided Magnetic Micro‐Agents

open access: yesSmall, EarlyView.
Image‐guided manipulation of magnetic micro‐agents requires localized fluorescence feedback capable of resolving dynamic interactions in confined environments. This study introduces a two‐photon endomicroscopy platform for real‐time motion tracking, multicolor micro‐agent discrimination, and imaging through biological tissue.

Transcranial photoacoustic computed tomography of human brain function

open access: yes, 2022
Herein we report the first in-human transcranial imaging of brain function using photoacoustic computed tomography. Functional responses to benchmark motor tasks were imaged on both the skull-less and the skull-intact hemispheres of a hemicraniectomy ...

Advances in research on layered double hydroxides for biomedical applications

open access: yesSmart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Single-stage approach for estimating optical parameters in spectral quantitative photoacoustic tomography

open access: yes
In quantitative photoacoustic tomography, the optical parameters of a target, most importantly the concentrations of chromophores such as deoxygenated and oxygenated hemoglobin, are estimated from photoacoustic data measured on the boundary of the target.

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

open access: yesVIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...
