摘要:
A surface acoustic wave (SAW) immunosensor for diagnosing allergy disease includes one or more SAW devices on each of which allergens derived from one allergy-causing substance are fixed and an allergen derived from another allergy-causing substance is not included, that is, allergens derived from different allergy-causing substances being fixed on different SAW devices; and a signal detector which detects an output signal from the SAW device. Also a method for diagnosing allergy disease is capable of measuring levels of allergen-specific IgE and total IgE in blood or another sample taken from a subject of diagnosis using a SAW immunosensor, the allergens being derived from various allergy-causing substances, thereby capable of effectively diagnosing allergy disease for various allergy-causing substances.

A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (10); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (20); and the upper end of the vertical fiber layer (20) becomes entangled so as to form a wave shaped wave layer (30) forming the uppermost portion of the fiber web.

A surface acoustic wave (“SAW”) device including a SAW element, a first material, a luminescence material and a light source, and a method for signal amplification of a SAW element. The first material may be positioned on the SAW element and bound to a target material in a sample. The luminescence material may be bound to the target material. The light source may apply light to the luminescence material. The SAW device and the method for signal amplification of a SAW element using the same allow amplification of a signal of the SAW element by an electromagnetic wave generated when light is applied to the luminescence material.

Provided is a multiple SAW sensor system capable of sensing a plurality of target materials in the SAW sensor with a single detector by using a multiplexer. According to the multiple SAW sensor system, the target materials in SAW sensors may be sensed with a single detector, thereby avoiding unnecessary power loss. Also, a plurality of target materials in a sample may be sensed, thereby reducing a waste of the sample.
