摘要： The present invention relates to methods and devices used for the formation of microconduits in a tissue. The term “microconduit” refers to a small opening, channel, or hole into, or through, a tissue, that allows transfer of materials by liquid flow, and by electrophoresis, the microconduit being formed upon impact of a plurality of accelerated microparticles with the surface of the tissue. A method is described for forming at least one microconduit in tissue including the steps of: accelerating a plurality of microparticles to a velocity that causes the microparticles to penetrate a region of tissue surface upon impingement of the microparticles on the tissue surface; and directing the microparticle towards the region of tissue surface, thereby causing the microparticles to penetrate the tissue and form a microconduit in the tissue. According to an embodiment, microparticles are accelerated by being hit with a moving, solid surface. In another embodiment, microparticles are accelerated by a flowing gas or liquid. Also described are methods and devices for using microconduits to deliver therapeutic molecules and ions into tissue, or for extraction of chemical analytes out of tissue. Also described is a method of nail piercing to accommodate jewelry.

摘要： A method is disclosed for treating tissue in response to a stimulus generated by the tissue. In one embodiment, the method transdermally treats an organism in response to a stimulus. In this embodiment, the medication is applied to epidermis of the organism, and the epidermis is electroporated in response to a stimulus, whereby the medication passes through the epidermis at a rate sufficient to alter the stimulus, thereby transdermally treating the organism. In another embodiment, the method measures a blood component content of blood. A portion of epidermis is electroporated to cause an aqueous fluid to be directed through an electroporated epidermis to a surface of the epidermis. Thereafter, the blood component content of the aqueous fluid is measured for correlation with a known aqueous fluid blood component content associated with a known concentration of blood component in the blood. The blood component concentration of the blood can thereby be measured. In still another embodiment, the method includes directing a medication to the tissue which can alter the stimulus when the tissue is electroporated, and electroporating the tissue in response to a stimulus, whereby the medication passes through the tissue in an amount sufficient to alter the stimulus, thereby treating the organism.

摘要： A method for measuring biopotential of an organism includes electroporating a portion of a tissue surface of the organism. The biopotential of the organism is then measured with electrodes at the electroporated portion of the organism. The portion of the organism that is electroporated can be, for example, a skin surface of the organism. A resistance-decreasing agent, such as heparin, sodium thiosulfate, thioglycolic acid solution and dithioglycolic acid can be applied to the tissue surface to facilitate reduction in electrical resistance. Another example of a resistance-decreasing agent is a keratin-disrupting agent, such as sulforhodamine. Examples of suitable biopotential measurements include electrocardiographic, electroencephalographic, electromyographic, electrohysterographic and elctrokymographic measurements. The method decreases skin resistance to diminish unwanted electrical voltages that compete with biopotential measurements, thereby significantly improving the biopotential measurement.

摘要： Transdermal transport of molecules during sonophoresis (delivery or extraction) can be further enhanced by application of an electric field, for example, electroporation or iontophoresis. In a preferred embodiment the ultrasound is low frequency ultrasound which induces cavitation of the lipid layers of the stratum corneum (SC). This method provides higher drug transdermal fluxes, allows rapid control of transdermal fluxes, and allows drug delivery or analyte extraction at lower ultrasound intensities than when ultrasound is applied in the absence of an electric field.

摘要： Detection or measurement of chemical indicator paramaters such as pH or of the concentration reactants of chemical reactions is accomplished by employing at least two fluorescent species with predominant emission at different optical wavelength regions, such that a synthesized fluorescence color change is created. In this manner, measurement is improved and simple visual inspection can reveal whether or not a chemical reaction or parameter has changed significantly, while retaining the sensitivity of fluorescence measurement or detection.
