General description

4-Aminothiophenol is a bifunctional aromatic thiol used to form self-assembled monolayers for biosensors.

4-Aminothiophenol (p-aminothiophenol, PATP) is an aromatic thiol. The self-assembly of silver and gold nano particles which are interconnected with 4-ATP to form metal-molecule-metal sandwich architecture has been characterized by surface enhanced Raman scattering (SERS) using an off-surface plasmon resonance condition. Chemical transformation of PATP to 4,4-dimercaptoazobenzene (DMAB) has been extensively studied.

Application

4-Aminothiophenol (4-ATP) was employed as bifunctional molecule to functionalize gold nanoparticles (NPs) used in surface-enhanced Raman spectroscopy (SERS) detection of thrombin by protein recognition.

It may be used in the following studies:
  • As a water insoluble ligand in the synthesis of pectin–4-aminothiophenol conjugates.
  • To functionalize gold nanorods (GNR) in the development of GNR nitrite sensor.
  • To form self-assembled monolayers (SAMs) of 4-aminothiophenol in the development of DNA biosensor.
  • As a linker to thiol (SH) functionalize multiwalled carbon nanotubes (MWCNTs).
  • To generate amino terminated self-assembly monolayers(SAMs) on platinum electrode which forms the base for attachment of single-wall carbon nano tubes (SWCTs).
