Study the Role of Mud-Like Psi Morphologies on the Performance of Aunps SERS Sensor for Efficient Detection of Amoxicillin

The specific form of mud-like structure Psi /AuNPS SERS sensors have been developed and experienced successfully. Two different forms of mud-like structure bare Psi layer SERS based substrate was created by a pulsed photochemical etching. A 50 % laser pulse duty cycle of laser wavelength of 410nm and laser power density of 300mW/cm(2) and 400mW/cm(2) in 20% ELF solution was employed to create the required Psi morphologies. The structural properties of bare mud-like structure Psi was improved by integrating AuNPS within the mud Psi layer by immersing method within the solution of 10(-3) M HAuCl4 to create well-organized and closely homogeneously distributed AUNPS hotspot gaps with steep specific surface areas SERS sensor. Specific features of bare mud-like structure Psi and SERS sensor were investigated by FESEM) images, photoluminescence (PL) measurements, (XRD) pattern and Raman microscope. The FE SEM images show, two various mud-like structures of linked and non- linked channels, and the pore-like structure of different dimensions was formed via changing the laser power density. The sensing performance of the developed SERS sensor is depended on the mud morphologies. An efficient detection process for ultra-low concentration of amoxicillin ranging from 10(-4) to 10(-10) M with an EF of5.5*10(8) and 8.4*10(10) was achieved with mud Psi layer of multifaceted mud-like and pore like structures of numerous slight pore dimensions. This improvement in the detection process is strongly owing to the higher value of the specific surface area of AuNPS and the density of small sizes of hot spots regions amongst them.
