Abstract: The present invention relates to a new type of metabolizable flower-like gold nanodandelion (GND), which possesses features: (1) large scale green synthesis with high monodispersity and a circa 100% yield; (2) cellular/physiological degradability; (3) precision control of the shape, petal number and size; (4) highly efficient radiotheranostics encompassing better enhanced CT contrast and pronounced x-ray induced ROS generation than conventional spherical AuNP.

Abstract: A sensing platform includes: a plurality of metal nanoparticles; a plurality of aggregate inducers each comprising first and second functional groups different from each other, and the first functional group of the aggregate inducers being in contact with the metal nanoparticles; and a plurality of recognition molecules for binding the metal nanoparticles and for interacting with a target to recognize the target, wherein the second functional group of the aggregate inducers is free from being in contact with the metal nanoparticles, and is used to induce the metal nanoparticles to aggregate after the recognition molecules interact with the target.

Abstract: An assembled pad includes multiple assembled mats connected to one another to define at least one cavity for receiving at least one subject matter. Each assembled mat is made of EVA and includes at least one tenon laterally extending therefrom and at least one mortise laterally defined to receive a corresponding one of the tenons of a corresponding one of adjacent assembled mats. The assembled pad has an undulated top surface for providing an excitation to an infant child who plays on the assembled floor. Each assembled mat has an irregular shape and a connecting edges between two adjacent assembled mats, and the subject matter and the assembled mats are flushed on each other for a smooth touch. The subject matter is a three-dimensional model such that the assembled pad has a vivid vision.
