In vivo laser Doppler holography of the human retina

open access: yes, 2018
The eye offers a unique opportunity for non-invasive exploration of cardiovascular diseases. Optical angiography in the retina requires sensitive measurements, which hinders conventional full-field laser Doppler imaging schemes.

External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

open access: yesAdvanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Clinical translation of laser speckle contrast imaging

open access: yes, 2022
Humankind is moving forward in an astonishing pace in every scientific specialty. It is therefore remarkable that the current standard-of-care for blood flow assessment has remained unchanged for decades. The desire to 'see' tissue perfusion (i.e.

Self‐Powered Permeable Electronic Dressing for Exudate Management, Electrostimulation and Drug Delivery in Chronic Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a self‐powered permeable electronic dressing (SPED) that synergistically integrates exudate management, electrical stimulation, and on‐demand drug delivery. The dressing effectively absorbs exudate while demonstrating potent antibacterial activity and accelerated tissue regeneration in diabetic mouse models, thereby promoting ...

Methods of producing laser speckle contrast images

open access: yes, 2014
Methods of imaging are provided. In some embodiments, the methods may comprise obtaining a raw speckle image of a sample, converting the raw speckle image to a laser speckle contrast image using a laser speckle contrast algorithm, and converting a laser speckle contrast image to a relative correlation time image using a relative correlation time ...

Influence of laser spot size at diffuser plane on the longitudinal spatial coherence function of optical coherence microscopy system

open access: yes, 2019
Coherence properties and wavelength of light sources are indispensable for optical coherence microscopy/tomography as they greatly influence the signal to noise ratio, axial resolution, and penetration depth of the system.

Unraveling the Heterogeneity of Cargo Distribution in the Exogenous Association of Proteins With Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
We characterized the distribution of cargo proteins associated with extracellular vesicles using various exogenous loading methods. In all cases, single‐particle analysis revealed that the distribution of protein content per EV is heterogeneous, following an exponential decay function.
