What isn't aluminum biocompatible?

Because it's a reactive form of metal and can easily form compounds. You wouldn't want a material in your body that's reactive otherwise you will be looking for more trouble.

Used to be aluminum. Some are acrylic now.

Beacause it is a metal.  The others are not.

What is not compatible?

Silicon is not good for the human body. Medical grade is mostly neutral (doesn't interact or interfere with the body and it's functions), and it is good for making prosthesis and artificial organs.

Try using Tom's of Maine Natural Deodorant. It is all natural and does not contain aluminum. It does come with a scent or scent free. You can find it in stores or health stores.

A few are:\nMg, Zn, Al, Fe, and Cu.  They will dissolve at different rates according to the activity series of the metals.

If you check at any good natural foods store with\na personal care products section, you should be able\nto find a large number of products that do not contain aluminum. Read the labels carefully!  Another\nalternative is a crystal deodorant stone, which you\nsimply wet and apply to the underarm.  I use one \nand like it a lot -- it's quite effective and about\nas basic as you can get in the way of ingredients --\njust minerals.

Are you looking for composites in biomedical fields?\n\nAnything used in biomedial applications has to produce as few allergic reactions as possible.  So some metals are out, since some people are allergic to metals.  Biomed pieces also have to be light, since it wouldn't help to have a prosthetic arm that weighs more than the rest of your body.\n\nSo composite materials are those that require several components, sometimes arranged in layers  Think for instance of carbon fiber.  It is made of several sheets that are soaked in pitch and baked to achieve a solid piece.   It is used in prosthetic limbs, and it is a composite that is non-metallic.  Carbon fiber is light, strong, and can be made into many shapes.\n\nHope this helps.

Syringe?  Amp can be given IM Gent can NOT.\n\nGent and Amp are not IV compatible in D51/2NS D5, or NS.

While we hate to think of those cute little animals being exposed to various materials, the alternative in many cases is to test them on humans.  There are, however, alternatives to animal testing of some kinds of materials.  There are synthetic membranes which react the same as  human or animal tissue with respect to testing of the corrosivity of a material.  These synthetic membranes cannot simulate the reaction of human or animal tissue to certain medicines or other non-corrosive materials.  In those instances, animal testing is the only choice before human testing.  Better an animal should suffer the ill effects of a test material than a human.  If you disagree, would you volunteer to be a test subject for an unknown medicine if the ill effects could possibly be debilitating or fatal?  Or would you prefer that the Dr. prescribe a medicine that could not be tested because animal testing was outlawed?

NO, it's not compatible

Lacking more detail - my suspicion is that the release of H2 will cause the amount of aluminium to be to high...\n\n-dh
