Photoacoustic (PA) imaging is an emerging technology that combines structural and functional imaging of tissues using laser and ultrasound energy. We evaluated the ability of PA imaging system to measure real-time systemic and microvascular mean oxygen …

Molecular imaging with photoacoustic ultrasound is an emerging field that combines the spatial and temporal resolution of ultrasound with the contrast of optical imaging. However, there are few imaging agents that offer both high signal intensity and …

Stem cell-based therapies have demonstrated improved outcomes in preclinical and clinical trials for treating cardiovascular ischemic diseases. However, the contribution of stem cells to vascular repair is poorly understood. To elucidate these mechanisms, …

A rational design of highly efficient photothermal agents that possess excellent light-to-heat conversion properties is a fascinating topic in nanotheranostics. Herein, we present a facile route to fabricate size-tunable reduced graphene oxide …

High intensity focused ultrasound (HIFU) thermal therapies are limited by deficiencies in existing image-guidance techniques. Previous studies using single-wavelength photoacoustic (PA) imaging have demonstrated that HIFU lesions generate contrast with …

A size and shape tuned, multifunctional metal chalcogenide, Cu2S-based nanotheranostic agent is deve- loped for trimodal imaging and multimodal therapeutics against brain cancer cells. This theranostic agent was highly efficient in optical, photoacoustic …

Photoacoustic Imaging for Medical Diagnostics …

Coupling graphene with a soft polymer surface offers the possibility to build hybrid constructs with new electrical, optical, and mechanical properties. However, the low reactivity of graphene is a hurdle in the synthesis of such systems which is often …

Converting nanoparticles or monomeric compounds into larger supramolecular structures by endogenous1,2 or external3,4 stimuli is increasingly popular because these materials are useful for imaging and treating diseases. However, conversion of …

Photoacoustic imaging (PAI) with a linear-array-based probe can provide a convenient means of im- aging the human microcirculation within its native structural context and adds functional information. PAI using a multielement linear transducer array …
