摘要： Electroadsorption and charged based biomolecule separation, concentration and detection with porous biosensors. In preferred embodiments, a potential is applied to a porous electrode to separate and concentrate molecules from solution. The bimolecular analytes are captured by the porous electrode itself, the same electrode that is used to generate the electric field for electroadsorption. In additional preferred embodiments, pH of the solution is adjusted to separate and concentrate biomolecules. Setting the pH equal to the protein isoelectric point was determined by the inventors to maximize concentration of biomolecules into the porous biosensor. The methods include simultaneously optically detecting charged molecules captured by the porous electrode. Methods of the invention are benign to biomolecules of interest, which are demonstrated to retain a high percentage of their activity after being released from the biosensor. Methods of the invention provide label-free detection. Advantageously, small voltages and ultrasmall volumes of solution are used in methods of the invention.

摘要： The present invention uses externally applied electromagnetic stimulus to control and heat porous magnetic particles and material associated with the particles. The particles contain magnetic material, such as superparamagnetic iron oxide and are associated with a material. Application of a DC magnetic field allows them to be moved with their associated material, and application of an AC RF electromagnetic field allows them to be heated with their associated material. The material can be associated with the particles by being contained in the pores of the particles, or in other cases the particles can adhere to the associated material, which can be an aqueous droplet. The present invention also provides a multi-layer porous magnetic particle. The particle includes a host layer having pores sized to accept magnetic nanoparticles. Magnetic nanoparticles are infused within pores of the host layer. An encoding layer includes pores that define a spectral code. The pores in the encoding layer are sized to substantially exclude the magnetic nanoparticles. The encoding layer can also be a multi-layer, exhibiting, for example, a complex spectral code.

摘要： The invention produces porous particles that produce a predetermined optical response and that may be manipulated magnetically. A preferred particle of the invention has a porous structure (12) that produces a predetermined optical response and magnetic material (14) adhered to the particle. Another preferred particle is amphiphilic. The optical response provided by a particle of the invention enables particles of the invention to be used in sensing, labeling, signaling, display and many other applications. The magnetic nature of the present magnetic particles permits the particles themselves to be manipulated, e.g., vibrated, moved, and re-oriented. The porous particles can also be used to control, move, and/or deliver small volumes of liquids and solids associated with the particles.

摘要： A method for imaging leverages the fluorescence lifetime of a fluorescent Si -containing particle to distinguish from background fluorescence. A particle is introduced into tissue. An excitation light pulse is applied to excite luminescence from the fluorescent Si-containing particle. Time-gated measuring of a responsive luminescence signal identifies the particle. In preferred embodiments the particle is coated or encapsulated with an organic material. The fluorescence lifetime of particles can be controlled during manufacture, such as by oxidation levels, quenching treatments, or by aging. This permits introducing and using groups of particles in imaging that have unique lifetimes and multiple time gating can be used to identify different particles or to monitor the change in lifetime of a single set of particles as they respond to a biochemical stimulus. The particles can also be functionalized for affinity to particular tissues and can be loaded with treatment molecules.

摘要： The invention is related to optical particles (10), use of optical particles in sensing applications, and methods of fabricating optical particles that can target a desired analyte. The invention is also related to the self assembly of individual optical particles. An advantage of the invention is that it includes self-assembling individual photonic crystal sensors onto a target. In an embodiment of the invention, a processed sensor structure having two generally opposing surfaces is provided, wherein each of the opposing surfaces have different surface affinities, with a first optical structure formed on one of the opposing surfaces, and a second optical structure formed on the other of the opposing surfaces. The chemically and optically asymmetric opposing surfaces will spontaneously align at an organic liquid/water interface. Changes in the optical response of at least one of the opposing surfaces indicate the presence of a particular analyte for sensing applications.
