Abstract: Camera phone accessories for using the camera phone to collect scientific data.

Abstract: A material comprising positively and negatively charged nanoparticles, wherein one of said nanoparticles contained a magnetically responsive element, are combined with a support molecule, which is a long natural or synthetic molecule or polymer to make a magnetic nanoparticle assembly. When the magnetic nanoparticle assembly is combined with cells, it will magnetize those cells. The magnetized cells can then be washed to remove the magnetic nanoparticle assembly and the magnetized cells manipulated in a magnetic field.

Abstract: This invention provides an apparatus and method that employs angle dependent light scattering combined with fractal dimension analysis of nanoparticle aggregates of gold and biopolymers, such as protein and nucleic acids, for detection and structural and functional characterization of unknown biopolymers. This is accomplished by detecting ADLS signal changes resulting from Au-biopolymer aggregate formation or from changes in fractal structure of Au-biopolymer aggregates as they specifically interact with other biopolymers. This invention describes an angle dependent light scattering apparatus that provides a sensitive, non-destructive, and dynamic measurement of the fractal dimension of Au-biopolymer aggregates, and provides a means for interpreting those measurements to allow identification of unknown nucleotides. A scattering cell is also provided.
