Technical Description A portablemagnetic surface Raman-enhanced scattering (SERS) nanoparticle arrays platform would be developed for magnetic separationSERS detection of environmental, water,biomolecules samples. It is very simplerapid platform with portable Raman spectroscopy to detect samples (bacteria, virous, water toxicants) after magnetic separation processes, without labelling the fluorescence dye,the limit of detection concentration is lower than 10-8 M.
Scientific Breakthrough The magnetic 2D nanosheets exhibit the magnetic separatingcollecting behaviors. After applied the external magnetic field, it is easy to captureconcentrate the samples (bacteria, virous, water toxicants). Furthermore, SERS effects produced by the noble metallic nanoparticles/2D nanosheets would be used to detect the samples by Raman spectroscopy. The samples of environmental toxicantsbiomolecules can be rapidly differentiated by the sensitivereproducible SERS signals, which can solve the time-consuming for the sample pretreatment.
Industrial Applicability The magnetic SERS detecting platform can not only magnetically separating environmental toxicantsbiomolecules, but also rapidly detecting them by SERS technique, for example, (1) biomolecules: microbes, antibiotic resistant bacteria, virus (COVID-19), DNA (adenine), -carotene (2) food safetydrugs: copper chlorophyll, narcotic (amphetamine), food toxicants (Aflatoxin B1) (3) water toxicants: malachite green, heavy metal ions detection.
