Special Issue Information
Dear Colleagues,
Photoacoustic imaging is a new type of non-invasive imaging technique that combines the high temporal and spatial resolution of ultrasound with the excellent spectral contrast of optics. In photoacoustic imaging, based on a ‘light in/sound out’ approach, the signals are generated by ultrasonic waves from the transient thermoelastic expansion of tissue upon near-infrared (NIR) light illumination. Here, some of the nanoscale inorganic materials (e.g., noble metal, metal chalcogenide, semiconductor, carbon-based nanoparticles) exhibit strong NIR light absorption to generate intense photoacoustic signals in deep tissue. These nanoparticles are often attached to molecularly targeted ligands to achieve effective systemic delivery. When the nanoparticles are tailored to gain spectrally separable contrast, they can allow multiplexed imaging to visualize multiple molecular targets or processes. Thus, the use of inorganic-nanoparticle-based contrast agents greatly extends photoacoustic imaging applications in disease diagnosis, drug delivery, targeted therapy, image-guided surgery, and biosensing.
This Special Issue will highlight the recent advances in inorganic nanoparticles for biological photoacoustic imaging in (but not limited to) the following topics: nanoparticle fabrication, nanoparticle assembly, nanoparticle coating, characterization method, imaging mechanism study, 1st NIR imaging, 2nd NIR imaging, multiplexing, multimodality, ratiometric imaging, activatable imaging, biomedical application, and clinical translation. Please consider contributing your original research articles, short communications, and review articles to this Special Issue. We looking forward to your response.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
