The primary purpose of this study was to determine the antimicrobial activity of functionalized single-walled carbon nanotube (SWNT) using an extract of the herb, Hempedu bumi. H bumi extract and H bumi extract complexed SWNT were evaluated for biological activities against Bacillus sp., (pathogen) Escherichia coli (opportunistic pathogen), and Aspergillus niger (pathogen).The formation of inhibition zones of these 3 microbes was measured to be evident for the functionalized SWNT with H bumi. Further, morphological and structural analyses were conducted to investigate the functionalized SWNT with H bumi using scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, X-ray powder diffraction, and Fourier transform infrared spectroscopy, well supporting the intact and crystalline nature of the SWNT. Fourier transform infrared spectroscopy result shows the highest peak at 3371.48 cm −1 , representing an andrographolide group from the plant extract. An apparent clear zone has been noticed with SWNT conjugated H bumi extract, displaying a zone of inhibition larger than 1.0 cm against the tested microbes. The results indicate that SWNT has the potential for use as a carrier of components from plant extracts.

“…Nanotechnology ("nanotech") deals the manipulation on an atom and molecular scale. It was subsequently reached a clear level with one dimension size ranged from 1 to 100 nanometers [5][6][7][8][9]. Nanotechnology and Nanoscience deal the ability to observe and to control the individual atom and molecule.…”

Nanocellulose prepared from the natural material has a promising wide range of opportunities to obtain the superior material properties towards various end-products. In this research, commercially available natural cotton was treated with aqueous sodium hydroxide solution to eliminate the hemicellulose and lignin, then cellulose was collected. The collected cellulose was subjected to acid hydrolysis using sulfuric acid to obtain nanocellulose. The prepared nanocellulose was further characterized with the aid of Fourier transform infrared spectroscopy, X-ray diffraction and Scanning Electron Microscopy to elucidate the chemical structure, crystallinity and the morphology.

“…In another work, Odeh et al have reported an amperometry biosensor for DENV2 serotype detection with LOD of 17 nM. The sensor is comprised of an immobilized dengue-specific DNA probe on Cu 2 CdSnS 4 quaternary alloy nanostructures deposited on an oxygen-etched silicon substrate (O 2 /Si) ( Odeh et al, 2017 ).…”

Last few decades, viruses are a real menace to human safety. Therefore, the rapid identification of viruses should be one of the best ways to prevent an outbreak and important implications for medical healthcare. The recent outbreak of coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus which belongs to the single-stranded, positive-strand RNA viruses. The pandemic dimension spread of COVID-19 poses a severe threat to the health and lives of seven billion people worldwide. There is a growing urgency worldwide to establish a point-of-care device for the rapid detection of COVID-19 to prevent subsequent secondary spread. Therefore, the need for sensitive, selective, and rapid diagnostic devices plays a vital role in selecting appropriate treatments and to prevent the epidemics. During the last decade, electrochemical biosensors have emerged as reliable analytical devices and represent a new promising tool for the detection of different pathogenic viruses. This review summarizes the state of the art of different virus detection with currently available electrochemical detection methods. Moreover, this review discusses different fabrication techniques, detection principles, and applications of various virus biosensors. Future research also looks at the use of electrochemical biosensors regarding a potential detection kit for the rapid identification of the COVID-19.
