Introduction In virtually all biological systems, calcium ions (Ca 2+) are essential intracellular signaling molecules, but they are particularly important in the nervous system. Ca 2+ is required for neurons to release synaptic vesicles, which is the major method by which they communicate with downstream neurons. Measuring increases in Ca 2+ concentration(More)
Nature–inspired algorithms are the most powerful algorithms for optimization problems. This paper presents a novel optimization channel allocation algorithm inspired by the flash pattern of fireflies that allows suppression of the four–wave mixing (FWM) crosstalk while maintaining channel bandwidth. It is composed of a fractional bandwidth channel(More)
Porous materials have potential applications in pho-tonic crystals, 1 membranes, 2 and data storage 3 and as catalyst supports. 4 Increasing interest in these areas has driven extensive research efforts to explore novel materials and processes. Although significant progress has been made in the development of new lithographic procedures for the fabrication(More)
This communication describes how thin porous films of metals on glass substrates can be conveniently and easily fabricated by the use of colloidal crystal templates and how these structures can find analytical applications in surface-enhanced Raman spectroscopy (SERS). Since the method of forming macroporous materials by templating with colloidal crystals(More)

We introduce a novel sensor scheme combining nano-photonics and nano-fluidics on a single platform through the use of free-standing photonic crystals. By harnessing nano-scale openings, we theoretically and experimentally demonstrate that both fluidics and light can be manipulated at sub-wavelength scales. Compared to the conventional fluidic channels, we(More)
Accumulated evidence demonstrated that long non-coding RNAs (lncRNAs) play a pivotal role in tumorigenesis. However, it is still largely unknown how these lncRNAs were regulated by small ncRNAs, such as microRNAs (miRNAs), at the post-transcriptional level. We here use lncRNA HOTTIP as an example to study how miRNAs impact lncRNAs expression and its(More)
Recently, many nanomedical studies have been focused on magnetic nanoparticles (MNPs) because MNPs possess attractive properties for potential uses in imaging, drug delivery, and theranostics. MNPs must have optimized size as well as functionalized surface for such applications. However, careful cytotoxicity and genotoxicity assessments to ensure the(More)
