An electronic-sensing & magnetic-modulation (ESMM) biosensor device and methods of using the same, where the device incorporates electrical, microfluidic, and magnetic subsystems. The device and methods of using such a device can be applied to high throughput point-of-care screening for the quantification and evaluation of a subject's immune response to pathogenic infections, which can be useful for: early diagnosis, stratifying high-risk subjects infected with a pathogen; and determining the status or effectiveness of a therapeutic response.

The invention relates to a method for forming an article comprising a pathway of particles wherein a termination of the pathway of particles is exposed. The method comprises arranging the particles by applying an electric field and/or a magnetic field at an interface between a water soluble or a non-water soluble matrix and a matrix comprising a viscous material and particles. After fixating the viscous material, the termination is exposed by dissolving the water soluble or non-water soluble matrix. The invention also relates to articles obtainable by said method, and to the use of said method in various applications.

A method of making an amalgamation preform includes providing a particle-liquid mixture containing a plurality of types of solid particles and a liquid base metal. The plurality of types of solid particles at least includes reactive particles, reactable with the base metal, and non-reactive magnetic particles. A magnetic field is applied to the particle-liquid mixture to magnetically disperse the plurality of types of solid particles in the liquid base metal to form a particle-liquid dispersion without substantially inducing a reaction between the reactive particles and the liquid base metal. A playdough-like amalgamation preform is prepared based on the particle-liquid dispersion without solidifying the liquid base metal.
