Abstract
Biosensor BS comprising at least one polymer P wherein said polymer P is a copolymer of at least monomer M and at least one ester E of (meth)acrylic acid and polyethylene oxide, wherein said monomer M is different from ester E and has at least one ethylenically unsaturated double bond, wherein polymer P has a surface adsorption SA of at least 200 ng/cm2 on the respective surface where polymer P is deposited, said SA being determined by quartz crystal microbalance.
Claims17
A biosensor BS comprising at least one polymer P,
- wherein said polymer P is a copolymer of at least monomer M and at least one ester E of (meth)acrylic acid and polyethylene oxide, wherein said monomer M is different from said ester E and has at least one ethylenically unsaturated double bond, and
- wherein said polymer P has a surface adsorption SA of at least 200 ng/cm2 on a respective surface where polymer P is deposited, said SA being determined by quartz crystal microbalance.
A bio-recognition element B having a surface O and comprising on said surface O at least one bioreceptor BR, wherein said surface O is at least partly coated with at least one polymer P,
- wherein said polymer P is a copolymer of at least monomer M and at least one ester E of (meth)acrylic acid and polyethylene oxide, wherein said monomer M is different from said ester E and has at least one ethylenically unsaturated double bond, and
- wherein said polymer P has a surface adsorption number SAN of at least 200 ng/cm2 on surface O, said SAN being determined by quartz crystal microbalance.
10-11. (canceled)
A process for making a bio-recognition element B, comprising:
- A) applying a solution S of at least one polymer P, wherein said polymer P is a copolymer of at least monomer M and at least one ester E of (meth)acrylic acid and polyethylene oxide, wherein said monomer M is different from said ester E and has at least one ethylenically unsaturated double bond, and wherein polymer P has a surface adsorption SA of at least 200 ng/cm2 on a surface O, and
- B) depositing at least one bioreceptor BR on the surface;
- wherein said B) depositing can be carried out before, during or after said A) applying.
