摘要:
A drug deactivation system according to some embodiments includes at least one drug-retaining region of a drug delivery device and at least one energy source coupled to the at least one drug-retaining region. The at least one drug-retaining region may be configured to retain a drug. The at least one energy source may be configured to transmit energy to the drug. The drug is capable of being rendered ineffective in the presence of the transmitted energy.
摘要:
A printed mask derived from a composition comprised of at least one compound including at least one alkaline-hydrolyzable group, and at least one compound including at least one ethylene oxide group. The printed mask is removable using an alkaline solution in about 30 seconds or less.
摘要:
A method and apparatus for measuring the presence or absence of interaction between at least a first and second material of interest by measuring osmotic pressure changes in an osmotic cell. Changes in osmotic pressure are determined by measuring the amount of compression exhibited by a compressible, semi-permeable material positioned in the cell.
摘要:
A drug deactivation system according to some embodiments includes at least one degradable capsule exposed to at least one drug-retaining region of a drug delivery device and an agent. The agent is configured to render a drug ineffective upon degradation of the at least one capsule. The at least one drug-retaining region is configured to retain one of the drug and the agent and the at least one capsule is configured to retain the other of the drug and the agent.
摘要:
A method and apparatus for measuring the presence or absence of reaction between a first and second material of interest by measuring osmotic pressure changes in a reaction cell. The reaction cell is capable of measuring the small changes in pressure that occur due to osmotic pressure shifts during a catalytic or binding reaction at species concentrations down to approximately 10−7 M.

摘要:
A sample manipulator that utilizes electrostatic traveling waves to selectively displace one or more samples deposited on its face is disclosed. The sample manipulator enables an operator to perform a wide variety of processes upon the deposited samples. Also disclosed are strategies for separating two or more samples, focusing a sample, and passing a reagent through a sample, all conducted on the face of the sample manipulator.
摘要:
An in situ chemical process for the preparation of toner comprised of(i) the provision of a latex, which latex is comprised of polymeric resin particles, an ionic surfactant and a nonionic surfactant;(ii) providing a pigment dispersion, which dispersion is comprised of a pigment solution, a counterionic surfactant with a charge polarity of opposite sign to that of said ionic surfactant, and optionally a charge control agent;(iii) mixing said pigment dispersion with said latex with a stirrer equipped with an impeller, stirring at speeds of from about 100 to about 900 rpm for a period of from about 10 minutes to about 150 minutes;(iv) heating the above resulting blend of latex and pigment mixture to a temperature below about the glass transition temperature (Tg) of the resin to form electrostatically bound toner size aggregates;(v) adding further aqueous ionic surfactant or stabilizer in the range amount of from about 0.1 percent to 5 percent by weight of reactants to stabilize the above electrostatically bound toner size aggregates;(vi) heating said electrostatically bound toner sized aggregates above about the Tg of the resin to form toner size particles containing pigment, resin and optionally a charge control agent;(vii) optionally isolating said toner, optionally washing with water; and optionally(viii) drying said toner.
摘要:
A system and method is provided for detecting concentration of an analyte in a fluid. A first container includes (i) an optical cavity detection region, (ii) a reservoir for one or more modifiers of one or more optical properties of the optical cavity detection region, and (iii) a set of one or more bounding regions through which objects in the fluid can transfer into the container. The optical cavity detection region and the reservoir define separate areas of the first container. The movement of the one or more modifiers between the reservoir and the optical cavity detection region is responsive to changes in concentration of the analyte. A second container includes an optical cavity detection region, and a set of one or more bounding regions through which objects in the fluid can transfer into the container. Also provided are optical components for guiding light into the optical cavity detection regions of the first and second containers.
