Patent number: 11385183Abstract: Cu(II) detection in the presence of main group heavy metal ions and d-, f- and g-element interferents relies on a colorimetric chelating complex between 3-hydroxy-5-nitrobenzaldehyde-4-hydroxybenzoylhydrazone (3-HNHBH) and Cu(II). Derivatives and entrapped forms of the probe were aligned with the methods of analysis, featuring spectrophotometric, reflectometric, lateral flow, microfluidic, lab-on-paper, positional array, dynamic array, flow cytometry and tandem stage devices. A remotely operating software capable of DFT calculations predicted the observed detection limit of 0.34 ?g L?1 (<5 nM) as well as high selectivity towards copper ions in the presence of competing Zn+2 and Ni+2. The probe was readily regenerated against metal complexation by using a 0.5 M HCl solution, indicating its feasibility to be a re-usable sensor for the convenient detection of copper ions in water-organic media.Type: GrantFiled: October 9, 2019Date of Patent: July 12, 2022Assignee: King Fahd University of Petroleum and MineralsInventors: Chanbasha Basheer, Abdulaziz A.

Patent number: 10883873Abstract: A rotating sample platform for SERS detection having sample holders for presenting a plurality of samples to a SERS laser at a speed and dwell time related to the Raman spectra. The sample holder may be designed to hold either slides or cuvettes, each of which contains either gold or silver nanoparticles. The sample holder for slides is configured for tilting each slide. The degree of tilt is captured by a wireless read head. A controller is configured to receive the wireless read head signals and the Raman spectra for each sample, correct the speed and dwell time and actuate a motor to rotate the sample platform at the corrected speed and dwell time. The rotating sample platform allows a set of slides or cuvettes in a sample holder to be presented to the SERS detector in a continuous manner, minimizing background corrections and sample adjustment time.Type: GrantFiled: October 17, 2019Date of Patent: January 5, 2021Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Tawfik Abdo Saleh Awadh, Abdulaziz Al-Saadi
