Special Issue Information

Dear Colleagues,

Thermal treatments are based on driving the normal temperature of the body (or part of it) at higher values in a controlled manner. Controlled temperature increments have a positive effect on patients with an ongoing disease, such as cancer. Thermal treatments include two techniques, namely hyperthermia and thermal ablation. The difference between these is the threshold of temperature: in hyperthermia, the temperature rises to 42 oC, while in thermal ablation, the temperature exceeds 42 oC. Thermal ablation is the basis of photothermal therapy (PTT). For this therapy, it is necessary to induce a temperature increase in the tumor, while keeping the temperature of the surrounding tissue at a normal level. This increase is achieved by irradiating the zone of the tumor with an energy source, mostly using a laser. However, when lesions that are close to large vascular structure need be treated, a part of the heat generated by the energy source is transferred into the blood flow, leading to a reduction of the potency of the thermal effect. To increase the efficacy and selectivity of photothermal ablation, it is necessary to introduce substances into the tumor to convert the absorbed the light into heat. Such substances are called photothermal agents (PA). To date, a vast array of nanoparticles capable of efficient heat generation under illumination with laser radiation have been developed.

We invite researchers to contribute original and review articles regarding the impact of PA on PTT. Potential topics include, but are not limited to:

  • Dyes
  • Metal oxide nanoparticles
  • Metallic nanostructures
  • Carbon-based nanomaterials
  • Nanoscale metal chalcogenides
  • Transition metal hidroalcogenide nanostructures

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 papers will be 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. Molecules 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 1800 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.

The photothermal effect of nanoparticles has proven efficient for driving diverse physical and chemical processes; however, we know of no study addressing the dependence of efficacy on nanoparticle size. Herein, we report on the photothermal effect of three different sizes (5.5 nm, 10 nm and 15 nm in diameter) of magnetite nanoparticles (MNP) driving the decomposition of poly(propylene carbonate) (PPC). We find that the chemical effectiveness of the photothermal effect is positively correlated with particle volume. Numerical simulations of the photothermal heating of PPC supports this observation, showing that larger particles are able to heat larger volumes of PPC for longer periods of time. The increased heating duration is likely due to increased heat capacity, which is why the volume of the particle functions as a ready guide for the photothermal efficacy. Full article
