In this communication, electrostatically assembled phthalocyanine (Pc)-DNA origami (DO) complexes are formed and their optical properties are demonstrated. The formation of the complex prevents the Pc aggregation, thus yielding an enhanced optical response and photooxidative resilience towards aggregation in biologically-related media. Simultaneously, the Pc protects the DO against enzymatic digestion. Both features solve previous drawbacks associated with phthalocyanine photosensitizers and DNA nanocarriers. The studied complexes may find use in technologies related to the photogeneration of singlet oxygen, e.g., photocatalysis, diagnositic arrays and photodynamic therapy.

: DNA nanostructures have emerged as intriguing tools for numerous biomedical applications. However, in many of those applications and most notably in drug delivery, their stability and function may be compromised by the biological media. A particularly important issue for medical applications is their interaction with proteins such as endonucleases, which may degrade the well-defined nanoscale shapes. Herein, fundamental insights into this interaction are provided by monitoring DNase I digestio...

Abstract Photodynamic therapy (PDT) is a promising approach for treatment of cancer and bacterial infection. Upon excitation by light, photosensitizers (PSs) produce reactive oxygen species (ROS), which could induce cell destruction. ROS could be produced via two kinds of photoreactions, which are type I (electron transfer) mechanism producing superoxide anions, hydrogen peroxides and hydroxyl radicals, and type II (energy transfer) mechanism generating singlet oxygen. Traditional type II PDT su...

: DNA is one of the most promising building blocks for creating functional nanostructures for applications in biology and medicine. However, these highly programmable nanomaterials (e.g., DNA origami) often require supraphysiological salt concentrations for stability, are degraded by nuclease enzymes, and can elicit an inflammatory response. Herein, three key strategies for stabilizing DNA nanostructures to conditions required for biological applications are outlined: 1) tuning the buffer condit...

As unique molecules with both therapeutic and diagnostic properties, porphyrin derivatives have been extensively employed for cancer treatment. Porphyrins not only show powerful phototherapeutic effects (photodynamic and photothermal therapies), but also exhibit excellent imaging capacities, such as near-infrared fluorescent imaging (NIRFI), magnetic resonance imaging (MRI), photoacoustic imaging (PAI), positron emission tomography (PET), and single-photon emission computed tomography (SPECT). I...

Immunotherapy is revolutionizing the treatment of cancer. It can achieve unprecedented responses in advanced-stage patients, including complete cures and long-term survival. However, immunotherapy also has limitations, such as its relatively low response rates and the development of severe side effects. These drawbacks are gradually being overcome by improving our understanding of the immune system, as well as by establishing combination regimens in which immunotherapy is combined with other tre...

In the endeavor of extending the clinical use of photodynamic therapy (PDT) for the treatment of superficial cancers and other neoplastic diseases, deeper knowledge and control on the subcellular processes that determine the response of photosensitizers (PS) are needed. Recent strategies in this direction involve the use of activatable and nanostructured PS. Herein both capacities have been tuned in two dendritic zinc (II) phthalocyanine (ZnPc) derivatives, either asymmetrically or symmetrically...

Lipids are important building blocks in cellular compartments, and therefore their self-assembly into well-defined hierarchical structures has gained increasing interest. Cationic lipids and unstructured DNA can co-assemble into highly ordered structures (lipoplexes), but potential applications of lipoplexes are still limited. Using scaffolded DNA origami nanostructures could aid in resolving these drawbacks. Here, we have complexed DNA origami together with a cationic lipid 1,2-dioleoly-3-trime...
