Atomically precise metal cluster enzymes for pathological tissue regeneration

open access: yesBMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Detection of Melanoma Metastases in Resected Human Lymph Nodes by Noninvasive Multispectral Photoacoustic Imaging

open access: yesInternational Journal of Biomedical Imaging, 2014
Objective. Sentinel node biopsy in patients with cutaneous melanoma improves staging, provides prognostic information, and leads to an increased survival in node-positive patients. However, frozen section analysis of the sentinel node is not reliable and

Highly Sensitive MoS2–Indocyanine Green Hybrid for Photoacoustic Imaging of Orthotopic Brain Glioma at Deep Site

open access: yesNano-Micro Letters, 2018
Photoacoustic technology in combination with molecular imaging is a highly effective method for accurately diagnosing brain glioma. For glioma detection at a deeper site, contrast agents with higher photoacoustic imaging sensitivity are needed.

Thermal intravascular photoacoustic imaging

open access: yesBiomedical Optics Express, 2011
Intravascular photoacoustics (IVPA)-a minimally invasive imaging technique with contrast related to optical absorption properties of tissue, can be used to visualize atherosclerotic plaques. However, the amplitude of photoacoustic signals is also related to a temperature dependent, tissue specific parameter-the Grüneisen parameter.

Photoacoustic guided ultrasound wavefront shaping for targeted acousto-optic imaging [PDF]

open access: yes, 2013
To overcome speed of sound aberrations that negatively impact the acoustic focus in acousto-optic imaging, received photoacoustic signals are used to guide the formation of ultrasound wavefronts to compensate for acoustic inhomogeneities.

Programmable three‐state nanoreactor for spatiotemporally controlled tumor therapy

open access: yesBMEMat, EarlyView.
The OMVs are shielded with a biocompatible Da–Ca shell, which prolongs its circulation period and promotes intratumoral accumulation. Importantly, the biocompatible Da–Ca shell can be controllably disintegrated in tumor microenvironment by using laser irradiation, generating in situ hyperthermia and releasing Ca2+.

Photoacoustics with coherent light

open access: yesPhotoacoustics, 2016
Since its introduction in the mid-nineties, photoacoustic imaging of biological tissue has been one of the fastest growing biomedical imaging modality, and its basic principles are now considered as well established.

Near‐infrared light‐activated aptamer‐based nanoprobe for spatiotemporally resolved detection of L‐lactate in colorectal cancer

open access: yesBMEMat, EarlyView.
A near‐infrared (NIR) light‐activated “lock‐key” nanodevice is reported for spatiotemporally resolved detection of intratumoral L‐lactate. The system stays silent until deep‐penetrating NIR light remotely unlocks its function, allowing for precise sensing within tumors.

Photoacoustic imaging of lymphatic pumping

open access: yesJournal of Biomedical Optics, 2017
The lymphatic system is responsible for fluid homeostasis and immune cell trafficking and has been implicated in several diseases, including obesity, diabetes, and cancer metastasis. Despite its importance, the lack of suitable in vivo imaging techniques has hampered our understanding of the lymphatic system.
