The detection of bio-molecules (e.g. nucleic acids and proteins) is the bedrock upon which research in the life sciences and diagnostic medicine rests. For nucleic acids, the polymerase chain reaction (PCR) is the ultimate in terms of target detection sensitivity (10s - 100s of copies/sample). For proteins, the enzyme-linked immunosorbent...
The study of granular matter is both scientifically intriguing and industrially important, yet it presents several unique characteristics and challenges. The discrete nature of granular materials often precludes the use of the continuum descriptions that are so commonly used for fluids, so alternative methods must be developed. Particles interact via...
Spontaneous regeneration in the adult mammalian central nervous system is rare, minimal, and generally does not lead to substantial functional recovery. Tissue engineering strategies to promote nerve regeneration aim to provide an environment that is physically and chemically engineered to enhance tissue formation. Strategic design of this environment is crucial...
The variable effects of self-awareness may be a result of multiple states of awareness being condensed under the umbrella term, "self-awareness". We posit that the cognitive and behavioral effects of self-awareness are largely dependent on another variable, level of abstraction, which modulates self-awareness on a continuum between conceptual and perceptual...
The porphyrazines (pzs), a class of porphyrin derivatives, have shown potential as therapeutic and imaging agents due to a combination of their near-IR absorbance/fluorescence and their enhanced chemical flexibility. Cell viability/proliferation assays and fluorescence microscopy were carried out in both tumor and normal cells to characterize the biological activity of...
In the Western classical art music tradition, a high level of music performance is achieved at the intersection of a musician's emotional, cognitive, and physical processes. Expert classical musicians have both an aural imagining of the sound they intend to produce and the physical associations of what it feels like...
