Special Issue Information
Dear Colleagues,
Nanomaterials, such as nanobubbles and nanodroplets, are submicron domains dispersed in solutions or on liquid/solid surfaces, which can survive for several hours or even days. It has been recognized that the stable existence of nanobubbles/nanodroplets may have significant effects on many important processes such as protein folding, peptide self-assembly, boundary slip, and activities of electrochemical reactions. Also, in recent years, nanobubbles have been widely used in water treatment, aquaculture, agricultural cultivation, health preservation, mineral flotation, and many other fields. However, the fundamental question of why surface and bulk nanobubbles can exist stably is still under debate because the paradox of a short lifetime predicted by the Epstein–Plesset theory and the observed long lifetime of nanobubbles in water has not yet been resolved. Moreover, many mechanisms of nanobubbles used in various applications, for example, aggregation states in different solutions, biological effects and interfacial properties, require further study.
Similarly, nanodroplets are used often in bioengineering and nanotechnology. Their advantageous properties of good biocompatibility, inertness, ultrasound responsiveness, high gas dissolution capacity, temperature-sensitive phase transitions, acoustic cavitation, versatility in imaging, and tunability make them valuable in biomedical, nanotechnological, and therapeutic applications. But how to control their size and concentration is key in their application in achieving high efficiency.
This Special Issue of Nanomaterials aims to present the current state of the art in the fundamental research of nanobubbles/nanodroplets and their applications. In the present Special Issue, we have invited contributions from leading groups in the field with the aim of giving a balanced view of the current state of the art in this discipline.

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. Nanomaterials is an international peer-reviewed open access semimonthly 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 2400 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.
