Special Issue Information

Dear Colleagues,

In the past decade, nano-technology has received extensive attention by researchers in wide range of area from energy and environments to biological and medical sciences, and considerable progress has been made. Particularly it has encompassed many cutting-edge research areas of nano-photonics and nano-optoelectronics with development of opto-electronic nanocomposites. The opto-electronic nanocomposites are materials that incorporate different metals, metal oxides or semiconductors-based nanoparticles into organic and inorganic or bio-molecules, and they show a drastic improvement in optical properties and electrical or thermal conductivity so that they play important roles in innovative development of opto-elctronic devices, photocatalysts, solar cells as well as nanoscale biomedical analysis and treatments of bio-molecules and living cells. Thus, it would be very worthwhile to shed new light on the recent advances in the nanomaterials science and technology by publishing a special issue entitled ‘New Opto-Electronic Nanocomposites: Synthesis and Applications’ in Nanomaterials. This special issue covers wide range of following topics, but not limited to 1) fabrications of opto-electronic nanocomposites; 2) their energy and environmental applications to develop solar cells and photocatalysts; 3) their biomedical applications to development of diagnosis and phototherapeutic techniques of cancer; 4) imaging and detection of single living cells and bio-molecules; 5) nano-transportation system of medicine. Many researchers in these interdisciplinary research fields are invited to contribute original full articles, communications or comprehensive review articles of latest works.

Although photodynamic therapy (PDT) is an effective, minimally invasive therapeutic modality with advantages in highly localized and specific tumor treatments, large and deep-seated cancers within the body cannot be successfully treated due to low transparency to visible light. To improve the therapeutic efficiency of tumor treatment in deep tissue and reduce the side effects in normal tissue, this study developed a near-infrared (NIR)-triggered upconversion nanoparticle (UCNP)-based photosensitizer (PS) carrier as a new theranostics system. The NaYF4:Yb/Er UCNPs were synthesized by a hydrothermal method, producing nanoparticles of a uniformly small size (≈20 nm) and crystalline morphology of the hexagonal phase. These UCNPs were modified with folic acid-conjugated biocompatible block copolymers through a bidentate dihydrolipoic acid linker. The polymer modified hexagonal phase UCNPs (FA-PEAH-UCNPs) showed an improved dispersibility in the aqueous solution and strong NIR-to-vis upconversion fluorescence. The hydrophobic PS, pheophorbide a (Pha), was then conjugated to the stable vectors. Moreover, these UCNP-based Pha carriers containing tumor targeting folic acid ligands exhibited the significantly enhanced cellular uptake efficiency as well as PDT treatment efficiency. These results suggested that this system could extend the excitation wavelength of PDT to the NIR region and effectively improve therapeutic efficiency of PSs. Full article

The efficient and selective delivery of therapeutic drugs to the target site remains the main obstacle in the development of new drugs and therapeutic interventions. Up until today, nanomicelles have shown their prospective as nanocarriers for drug delivery owing to their small size, good biocompatibility, and capacity to effectively entrap lipophilic drugs in their core. Nanomicelles are formed via self-assembly in aqueous media of amphiphilic molecules into well-organized supramolecular structures. Molecular weights and structure of the core and corona forming blocks are important properties that will determine the size of nanomicelles and their shape. Selective delivery is achieved via novel design of various stimuli-responsive nanomicelles that release drugs based on endogenous or exogenous stimulations such as pH, temperature, ultrasound, light, redox potential, and others. This review summarizes the emerging micellar nanocarriers developed with various designs, their outstanding properties, and underlying principles that grant targeted and continuous drug delivery. Finally, future perspectives, and challenges for nanomicelles are discussed based on the current achievements and remaining issues. Full article

Issues related to global energy and environment as well as health crisis are currently some of the greatest challenges faced by humanity, which compel us to develop new pollution-free and sustainable energy sources, as well as next-generation biodiagnostic solutions. Optical functional nanostructures that manipulate and confine light on a nanometer scale have recently emerged as leading candidates for a wide range of applications in solar energy conversion and biosensing. In this review, recent research progress in the development of photonic and plasmonic nanostructures for various applications in solar energy conversion, such as photovoltaics, photothermal conversion, and photocatalysis, is highlighted. Furthermore, the combination of photonic and plasmonic nanostructures for developing high-efficiency solar energy conversion systems is explored and discussed. We also discuss recent applications of photonic–plasmonic-based biosensors in the rapid management of infectious diseases at point-of-care as well as terahertz biosensing and imaging for improving global health. Finally, we discuss the current challenges and future prospects associated with the existing solar energy conversion and biosensing systems. Full article
