Special Issue Information
Dear Colleagues,
Over the last two decades, a large number of nanoparticle delivery systems has been developed and approved for clinical use in cancer diagnosis and therapy. In contrast with the commonly used small molecule drugs that present a wide range of biodistribution, low specificity, and high toxicity, nanoparticles (NPs) can improve the pharmacological response. The importance of these macromolecules is based on their nanoscale attribute (1–100 nm), being accumulated in the tumor tissue through a passive mechanism known as enhanced permeability and retention (EPR) effect because of the increased vascular permeability in the tumor region. They include different classes, based on their structure, sizes or inorganic or organic natures depicting some of them, and biologically attractive properties such as biocompatibility and biodegradability. Furthermore, the incorporation of active targeting using molecules (ligands, antibodies, peptides, and RNA aptamers) that can be recognized specifically by receptors on the surface of the cell membrane has increased nanoparticle uptake by tumor cells. These biotechnological advances in functionalizing nanoparticles combined with multiple classes of chemotherapeutics, siRNAs, and plasmids for packaging and delivering into tumor cells have improved efficacy and reduced toxicity over conventional cancer treatments. Undoubtedly, an exciting scenario has been created: new formulations for conventional chemotherapy drugs or the development of new use for existing antitumor drugs. Moreover, the major challenges are how different combinations of nanoparticle delivery systems can be rationally designed so that safety and efficacy are maximized, and to understand and develop tools to evaluate the biological responses to these nanoparticles.

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. Biomolecules 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 2700 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.
