Special Issue Information
Dear Colleagues,
The sensing of chemical and biological materials has greatly advanced due to the development of miniaturized sensors, portable energy sources, and sophisticated communication modules and signal processing algorithms.
However, sample introduction remains a critical bottleneck, often limiting the deployment of sensors in field applications. In many cases, samples must be transported to laboratories for complex preparation, which hinders real-time and on-site analysis.
This Special Issue aims to highlight innovative sample introduction methods that enable the sensing of materials not accessible via classical techniques. For example, non-volatile pharmaceuticals may require vaporization without degradation and with minimal energy input. Similarly, solid-state sensors designed for liquid-phase analysis often require the manual dissolution of samples prior to sensing—a process that must be adapted for field use with low energy and minimal technical skill.
We welcome contributions on a broad range of sample introduction technologies, including but not limited to the following:
- Thermal desorption of solid samples;
- Enrichment of gaseous samples using adsorption tubes;
- Cyclone-based enrichment devices;
- Plasma evaporation techniques such as:
- Desorption Electrospray Ionization (DESI);
- NanoDESI (Nanospray DESI);
- Direct Analysis in Real Time (DART).
Laser-based Ambient Ionization methods:
- MALDESI (Matrix-Assisted Laser Desorption Electrospray Ionization);
- LAESI (Laser Ablation Electrospray Ionization);
- Paper Spray Ionization (PSI);
- Easy Ambient Sonic-Spray Ionization (EASI);
- Low-Temperature Plasma (LTP).
This Special Issue aims to showcase research that bridges the gap between laboratory-grade sample preparation and practical, field-deployable sensing solutions.

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. Sensors 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 2600 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.
