Couple of things:

Small amount of metal in the shot, like what was in the Japan batch of Moderna.

Are the needles magnetic; if so maybe part got left behind :0

If there wasn’t a lump moving with the magnet, I’d think that maybe the person’s skin had been damp.

Did you say "metal"? :) Funny you should mention that.

Graphene Oxide Based Metallic Nanoparticles and their Some Biological and Environmental Application

Let me first skip to keywords:

Keywords: Graphene oxide; decoration; drug delivery; metallic nanoparticles; photocatalytic degradation; pulsed laser ablation.

Now back to the top

Abstract

Background: Recently the decoration of graphene with metallic nanoparticles by a synchronized reduction of graphene oxide (GO) and synthesis of metallic nanoparticles has gained momentum. Metal-decorated carbon substrates, for example, carbon nanotubes and graphene oxide have been of interest to the scientific group all through the past three decades on account of different potential applications. The utilization of graphene oxide as the nano scale substrates for the formation of nanocomposites with metal oxides is a novel thought to acquire a hybrid which would show both the properties of GO as an interesting paper-shape material and the elements of single nanosized metal particles.

Results:

Grapheme-metal oxide composites are gaining attention as a viable alternative to boost the efficiency of various catalytic, storage reactions in energy conversion, anticancer and drug delivery applications. Nevertheless, by combining the superior physical/chemical properties of GO themselves and the versatile nanomaterials that can decorate with GO, GO based materials have a bright future in the anticancer, drug delivery, energy, and environmental applications.
