Despite being marketed as toys, water beads could pose a serious danger to children as if swallowed, could expand inside a child and cause bowel obstruction – which needs surgery to remove.
A microbead imaged using scanning electron microscopy. Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension [4] when they are first created, and are typically created using material such as polyethylene (PE), polyethylene terephthalate (PET), nylon (PA), polypropylene (PP), and polymethyl methacrylate (PMMA).

Silica beads are a key element to this method, which are capable of binding the nucleic acids in the presence of a chaotropic substance according to the chaotropic effect. This method is one of the most widespread [ 6 ] [ 7 ] methods for isolating nucleic acids from biological samples and is known as a simple, rapid, and reliable [ 2 ] method ...
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).

Colloidal silica gel with light opalescence. Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or vacuum.
