The invention belongs to the field of biomedicine, and particularly relates to a glucose core, comprising a glucose and/or a glucose hydrate, a diluent and a binder, wherein, the glucose and/or the glucose hydrate is present in the glucose core in an amount of &#x2264;85% by weight percentage; and relates to a glucose pellet comprising the glucose core and a laminated layer coating the glucose core; and further relates to a pharmaceutical composition comprising the glucose pellet. The glucose pellet or the pharmaceutical composition of the invention are useful in treatment and/or assistant treatment of a glycogen storage disease and/or a diabetes.

Glucose pellets, preparation method and use thereof

Provided is a method for preparing gold nanorods having a high catalytic activity by using a femtosecond laser. The method includes: (1) preparing a gold seed solution; (2) preparing a gold nanorod solution by a seed solution growth process; (3) subjecting the gold nanorod solution to a centrifugal separation to obtain the gold nanorods, and dropping the gold nanorods on a silicon substrate; (4) building a system for preparing the gold nanorods having the high catalytic activity by using the femtosecond laser; and (5) emitting a pulse of the femtosecond laser on the silicon substrate, to allow an electric field distribution of a surface of the gold nanorod on the silicon substrate to change, to partially exfoliate atoms on the surface of the gold nanorod, thereby obtaining the gold nanorod with the high catalytic activity.
