Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

open access: yesAdvanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Ready to participate? Using qualitative data to typify older adults’ reasons for (non-) participation in a physical activity promotion intervention

open access: yesBMC Public Health, 2019
Background A sufficient amount of regular moderate physical activity (PA), at least 2.5 h of moderate to vigorous PA per week as recommended by the WHO, is one of the most important lifestyle factors for maintaining good health in old age.

CPP–PEG‐Guided Surface Engineering of Mitochondria Enables Efficient Cellular Uptake and Respiratory Modulation

open access: yesAdvanced Materials Interfaces, EarlyView.
PEG‐guided mitochondrial surface engineering supports structural stabilization and controlled presentation of cell‐penetrating peptides. CPP–PEG‐modified mitochondria exhibit enhanced cellular uptake and uptake‐associated respiratory modulation, providing a proof‐of‐concept framework for modular organelle engineering and future bioenergetic modulation ...

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

open access: yesAdvanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Understanding Social Responsibility Using the Theory of Planned Behavior: The Connecticut Gatekeeper Program

open access: yes, 2015
The public is often encouraged to engage in socially responsible behaviors for the good of society, sometimes on behalf of those most vulnerable; older adults are one such rapidly growing vulnerable population.
