A microfluidic device including a serum separator, a quantum dot and antibody inlet connected to the serum separator, a quantum dot linked immunosorbent assay (QLISA) chamber connected to the serum separator, and an outlet connected to the QLISA chamber. The microfluidic device is configured to determine an amount of drug in a serum.

Microfluidic device

According to exemplary embodiments, a method of synthesizing tin (Sn)-doped Zinc Sulfide (ZnS) nanostructures for electroluminescent white light source includes coating a substrate, including a silicon oxide layer, with Sn by vacuuming depositing Sn as catalyst nanostructures on the substrate, placing the substrate coated with Sn in a furnace, introducing a carrier flow gas into the furnace, adding a ZnS power to the furnace, growing ZnS nanostructures, and dissolving Sn in the growing ZnS nanostructures. The S vacancies are on a surface of the ZnS nanostructures. The ZnS nanostructures are grown on the substrate having a temperature in a range of 750&#xb0; C. to 850&#xb0; C.

Sn doped ZnS nanowires for white light source material

A method of synthesizing catalyst doped ZnS nanostructures including preparing a silicon substrate by vacuum depositing a metal catalyst nanostructure on an ultrathin silicon oxide layer, doping a zinc sulfide (ZnS) nanostructure with a catalyst of the metal catalyst nanostructure including at least one of gold (Au), manganese (Mn), and tin (Sn), and modulating ZnS intrinsic defects by the concentration of the catalyst and the size of the ZnS and metal catalyst nanostructures, in which the catalyst is dissolved in a nanowire of the ZnS nanostructure during growth, the concentration of the catalyst in the nanowire is dependent on the size of the catalyst, and the doping is tuned by growth conditions.
