The team has tested HoloHands by moving silica microspheres using the lab's otherwise standard infrared holographic laser system.

These "microspheres" were made by a division of Akzo Nobel in the Netherlands.

Additionally, the nanofibers in these hollow microspheres do not generate much degradation byproducts that could hurt the cells, he says.

Tests in mice and guinea pigs have shown that such vaccine microspheres are as safe and effective as conventional shots.

He suggested an infusion of radioactive microspheres into her liver, another procedure she'd never heard of, to treat the liver tumors without chemotherapy.

Page turning was slow and was accompanied by a distracting flash of black as the microspheres dived down into their oil-filled nodules before forming new text.

Ma says the nanofibrous hollow microspheres are highly porous, which allows nutrients to enter easily, and they mimic the functions of cellular matrix in the body.

In addition to that, because the sugar-glass coats the vaccine molecules and thus isolates them, various vaccines in their own microspheres can be mixed together in a single jab.

The new vaccine microspheres, on the other hand, can be injected straight into the body, eliminating those sorts of mistake and with them the need for the preservatives found in ordinary vaccines.
