Bioengineered nanomaterials have inspired revolutionary imaging and drug delivery methods, whose clinical application in cancer research has resulted in powerful medical devices for early diagnosis, treatment, and prevention of cancer. Recent advances in super imaging agents have resulted in improved resolution and sensitivity. For instance, fluorescent quantum dots with wavelength-tunable emissions, plasmon-resonant gold nanostructures with shape-controlled near-infrared absorptions and MRI-active iron oxide nanoparticles are well established molecular imaging probes for cancer and noninvasive tumor imaging. Nanomaterials are also considered to be the most effective vectors that can break through transport biobarriers and target a constant dose of multiple therapeutic agents to tumors and intracellular endocytic compartments for cancer gene therapy, immunotherapy, or chemotherapy. Furthermore, nanowire- or nanotube-based electronic devices demonstrate extraordinary sensitivity capable of detection at the single molecule or protein level. It is anticipated that developing nanotechnology-driven imaging, sensing, and therapeutic systems will dramatically advance cancer research and clinical treatments.

We organize this special issue aiming to visualize the current progress in the emerging multidisciplinary field of cancer nanomedicine. We invite researchers to submit original research and review articles associated with the following topics. Potential topics include, but are not limited to:

• Synthesis, functionalization, and characterization of nanomaterial-based diagnostic or delivery tools
• Nanomaterial-induced compartmental activities in cancer cells
• Nanotechnology-driven bioimaging and cancer diagnosis
• Tumor-specific or targeted drug delivery
• Nanomaterial-mediated cancer gene therapy
• Organic or inorganic nanoparticle delivery/adjuvant systems for cancer immunotherapy
• Nanomaterial-based biosensors/assays for cancer diagnosis or assessments of therapeutic efficacy
• Toxicity and clearance kinetics of nanomaterials
• Review of recent works on cancer nanomedicine
