Abstract: A new pandemic named as COVID-2019 (coronavirus disease 2019) has stunned the world. This pandemic situation arises due to an enormous death toll of human lives across the world by the infection of SARS-CoV-2 that results in pneumonia-associated respiratory syndrome. It is repentantly observed to speedy spread over the world day by day because of need in rapid detection, proper medication, and proven treatment. Since it's evolved in November 2019, scientists were engaged to find its genome code. However, the current efforts of the scientist (both physical and biological) in the world is to invent specific antiviral drugs and physical therapeutic against COVID-19 and rapid detection method. Hence we have tried to discuss in this report rapid detection system of the viral genome like +ssRNA, and S (spike) - protein containing into SARS-CoV-2 by magnetic nanoparticles (MNPs). To detect SARS-CoV-2 pathogens, giant magnetoresistive (GMR) biosensor along with MNPs may play a significant role. We expect that this detection system will be an effective challenge to control the outbreak of COVID-19.

Abstract: Lanthanum titanium oxide thin films are sometimes used in high-temperature environments. Therefore, it is worth paying attention to the thermal stability of the La2Ti2O7 films. La2Ti2O7 target was made through traditional solid-state reaction way to study the effect of substrate temperature on the characteristics of LTO thin films; A Set of lanthanum titanium oxide thin films has been deposited on to Si (100) substrate through Pulsed laser deposition at different annealing temperatures. The results of X-ray diffraction indicated that the prepared LTO thin films at temperatures up to 700°C are amorphous, while the profilometer Dektak-XT conducted to determine the thickness and roughness of La2Ti2O7 films. The obtained result pointed that the thin film thickness decreased by increasing annealing temperature linearly, and the roughness was inversely proportioning to the increasing of substrate temperature. The value of the lowest roughness equal to 12.28 nm for the thinner film with a thickness of 253.46 nm, while the highest roughness was found to be 14.74 nm for the thicker film at 323.05 nm, which were deposited at 700°C and 500°C respectively, therefore it has been remarked that the annealing temperature influenced the morphology, thickness, and roughness of the LTO thin film.
