The present invention discloses a chemically surface-treated plastic slide that
is useful for the immobilization of proteins, peptides or small molecules to its
surface for the fabrication of biochips. Also disclosed in the present invention
is a surface-treated plastic slide made of polystyrene, which is useful for the
immobilization of oligonucleotides or polynucleotides to its treated surface for
the fabrication of DNA chips.
