    Lighting the future: Perovskite nanorods and their advances across applications
    (Elsevier Ltd., 2024) Aftab, Sikandar; Li, Xin; Kabir, Fahmid; Akman, Erdi; Aslam, Muhammad; Pallavolu, Mohan Reddy
    This in-depth analysis explores the many uses of perovskite nanorods (PNRs), which is a class of materials with remarkable optoelectronic characteristics that are produced by efficient synthesis methods. PNRs are remarkably versatile in various technological domains. The following are some of their most important applications. First, we have comprehensively described innovative/efficient manufacturing techniques that are used in order to produce high-quality properties PNRs materials. The high surface-to-volume ratio of PNRs and other optoelectronic characteristics are then useful in regards to raising solar cell efficiency. Furthermore, they are essential for light-emitting diodes (LEDs) and photodetectors (PDs), which help in order to enhance the performance in these applications. PNRs can be used in solid-state lighting by taking advantage of their special optoelectronic properties. PNRs are appropriate for various sensing applications due to their high surface-to-volume ratio, which makes advanced sensing capabilities possible. Moreover, PNRs offer advantages in non-volatile memory applications due to their resistive switching behavior, which supports resistive random-access memory (RRAM) devices. PNRs hold potential for quantum optics and communication developments in specific applications, such as polarized light detectors and nanolasers. Continuous investigations proactively tackle these matters by withstanding obstacles to stability and ecological worries, which enable PNRs to reach their maximum potential in various technological uses. The key to realizing the enormous potential of PNRs across a wide range of applications is simply to unlock their door.

    Recent advances in nanomaterials based biosensors
    (Elsevier Sci Ltd, 2023) Aftab, Sikandar; Abbas, Aumber; Iqbal, Muhammad Zahir; Hussain, Sajjad; Kabir, Fahmid; Akman, Erdi
    Low-dimensional materials can be used to create highly sensitive, targeted, label-free, FET biosensors that can identify a variety of analytes. However, reliable biological FET is not yet available in the real world because it is hard to meet the strict requirements for highly sensitive and selective bio-FET fabrication. Two-dimensional materials, like graphene or transition metal dichalcogenides (TMDs), are used in devices called 2D FET-based biosensors as the active channel in a field-effect transistor (FET) configuration. 2D materials, are better candidates for high-performance biosensing due to their dramatic change in resistivity upon analyte adsorption or biomarkers detection, tunable electronic properties, high surface activities, sufficient stability, and layerdependent semiconducting properties. We provide a brief overview of fascinating biosensing applications with a variety of architectural designs in this review article. This group of devices includes 2D TMDs-based FETs that incorporate graphene, reduced graphene oxide, quantum dots, nanoparticles, nanocomposites, nanorods, nanospheres, nanoflowers, and TMD/MXene heterostructures. These achievements show the exceptional capability of ultrahigh performance in biomarker detection in point-of-care diagnostics. The conclusion includes a summary of current opportunities and challenges.
