An infrared fluorescent particle comprising a functional group or a substance that is capable of binding to an analyte, wherein fluorescence at infrared wavelength is emitted from the particle upon exposure of the particle to excitation light at infrared wavelength. The infrared fluorescent particle of the present invention is capable of binding to the analyte. Due to a high penetration of the fluorescence and the excitation light into biological substances; the infrared fluorescent particle of the present invention can reduce an influence of luminescence, light absorption or light scattering which is occurred due to the analyte and the surrounding substances.

A grip comprises a grip body forming a gripping control portion of a manually operable device to be held with the operator's palm and fingers. The grip body includes a ball-receiving surface coming into contact with the ball of the thumb, a palm-receiving surface coming into contact with a middle portion of the palm and the ball of the little finger, a finger-receiving surface coming into contact with the fingers, an open surface positioned between the tips of the fingers and the ball of the thumb for receiving the thumb when the grip body is held, and a switch mounted on a top portion of the grip body to be operable with the thumb. The grip body further comprises a thumb-guiding portion in the form of a shallow groove formed at an upper part of the ball-receiving surface of the grip body, the inside of the first joint of the thumb being placed along the thumb-guiding portion when the switch is operated, and a rising portion formed on at least either one of portions between the thumb-guiding surface and the open surface and between the thumb-guiding surface and the palm-receiving surface for applying resistance when the operator's hand advances into the switch.
