“…We compared the diameter of S. aureus with E.coli , which indicates higher resistance of S. aureus to CdO NPs. The prepared NPs damaged the bacterial cell membrane inhibiting the metabolic enzymes activity present on bacterial cell membrane, which ultimately leads to cell death (Kannan, Radhika, Nikolova, et al, 2020; Karthik, Nikolova, et al, 2020). Previous studies indicated that small particle size, reactive oxygen species generation (ROS) and release of CdO 2 + ions facilitate to establish electrostatic interaction between bacterial cell surface and NPs (Aswini et al, 2020; Kannan, Dhanuskodi, et al, 2020; Kannan, Radhika, Vijayalakshmi, et al, 2020) as shown in Figure 7.…”

“…The formation and stability of the prepared CdO NPs was analysed within 250–650 nm of absorption range. The spectra was recorded through UV–Vis Halo DB‐20 spectrophotometer (Dynamical Ltd, Sydney, Australia), which was dispersed in ethanol (Kannan, Radhika, Nikolova, et al, 2020; Karami, Jamshidian, & Zakariazadeh, 2019; Karthik, Nikolova, et al, 2020; Saqib et al, 2019). The spectrophotometer worked in the reflection mode at a resolution of 1 nm.…”

“…Potassium bromide (KBr) pellet method was used to test the biomolecules by IR spectroscope (Schimadzu FTIR‐4200, Japan). The sample was scanned between 400 and 4,000 cm −1 at a resolution of 4 cm −1 in transmittance mode (Baghayeri et al, 2018; Karthik, Nikolova, et al, 2020; Nosrati et al, 2018; Pakiyaraj et al, 2019).…”

Microbial mediated synthesis of metallic nanoparticles constitutes as effective and promising approach for the development of antibacterial materials in the field of bioengineering and biomedicine. We prepared Cadmium oxide nanoaprticles (CdO NPs) utilizing Penicillium oxalicum, and cadmium acetate solution via coprecipitate method. The elemental composition and morphology of these synthesized CdO NPs were examined through X-ray diffraction (XRD), UV-Vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and Energy dispersive spectroscopy (EDS). Furthermore, we evaluated the bactericidal potential of prepared CdO NPs using Escherichia coli (E.coli), Staphylococcus aureus (S.aureus), Bacillus cereus (B.cereus), and Pseudomonas aeruginosa (P. aeruginosa). Dimethyl sulfoxide was used as negative control while erythromycin was used as positive control. The XRD spectrum revealed cubic crystalline nanoparticles with 22.94 nm size and UV showed absorbance peak at 297 nm with 2.5 eV band gap energy. FTIR depicted O─H and carboxylic groups along with CdO stretching vibration. EDS showed the presence of organic compounds on Cd and O over NPs surface. SEM results revealed the spherical shape of the CdO NPs. The synthesized NPs exhibited highly potent bactericidal activity against selected strains and demonstrated less optical density of 0.086 after 24 hr. Owing to the significant antibacterial activity of CdO NPs, the broad application prospects of these nanoparticles CdO NPs in extensive biomedical applications is indicated.

“…While the biosensor is not an alternative to clinical diagnostics, the scientists see the system potentially operating in crowded environments. For ease of use, the integrated system will be a portable device that can be used for rapid detection in public areas, such as train stations and hospitals [45,46]. To find the virus on time and accurately, the sensor combines two different effects: optical and thermal.…”

Pandemic is not a word to use lightly or carelessly. It is a word that, if misused, can reason difficult fear, or unwarranted acceptance that the fight is over, foremost to needless suffering and fatality. Coronavirus disease of 2019 (COVID-19) has become a deadly disease shaking the whole world. All the countries are facing a crisis in disposing of fast diagnostics of the syndrome, able to be organized to a wide number of persons. To control the spread of this virus harmful results of coronavirus have given rise to the growth of analysis tools. In this urgent situation, many researchers and scientists are working on finding a solution to control the deadly virus. In this chapter, we focused on researching biosensors that could detect the virus in the air. People breathe about 11,000 L of polluted air that is invisible. The major purpose of this sensor is, it could be used as another method and more significant to calculate the concentration of virus in the air, but it won't be the replacement for laboratory tests. Advanced technology, time-consuming and low-cost equipment for this disease spreading virus is in need to control the pandemic at the earliest. This biosensor is prevalent and can detect even minute amounts of viruses present in the air and surroundings.

TiO2 nanoparticles were successfully synthesized using a facile and scalable sol-gel method and their structural and optical properties studied. XRD ad FTIR was used to identify the phase, crystallite size, and functional groups present in the nanoparticles. The prepared samples crystallize in the anatase structure with highly crystalline order. TEM/EDX shows that the nanoparticles are pure, spherical, and with an average particle size of 15 ± 2 nm. The bandgap energy was 3.59, 3.79, and 3.64 eV, respectively. PL emission is attributed to oxygen vacancies (Vo). The calcination temperature at 450 °C suggests a better photocatalytic performance under visible light compared with other sample's thermal treatments.
