Nanotechnology has significantly advanced the detection of plant diseases by introducing nano-inspired biosensors that offer distinct advantages over traditional diagnostic methods. These biosensors, enhanced with novel nanomaterials, exhibit increased sensitivity, catalytic activity, and faster response times, resulting in improved diagnostic efficiency. The increasing impact of climate-induced stress and emerging plant pathogens have created an urgent demand for real-time monitoring systems in agriculture. Nanobiosensors are revolutionizing plant disease management by enabling on-site detection of pests and weeds, facilitating precise pesticide applications. This article provides a comprehensive overview of the development and application of nanobiosensors in real-time plant disease diagnosis. It highlights key innovations, such as smartphone-integrated nanozyme biosensing and lab-on-a-chip technologies. Special emphasis is placed on the detection of molecular biomarkers, demonstrating the critical role of nanobiosensors in addressing the evolving challenges of plant disease management and agricultural sustainability. © © 2025 Narware, Chakma, Singh, Prasad, Meher, Singh, Bhargava, Sawant, Pitambara, Singh, Manzar and Kashyap.
Neuroprotective Effect of Ginkgo Biloba and its Role in Alzheimer’s Disease
(Bentham Science Publishers, 2022) Divya Raj Prasad; Bipin Maurya; Aparna Mishra
Alzheimer's disease (AD) is a common age-related neurodegenerative disorder that results in cognitive defects. The disease is a progressive, age-associated, irreversible, neurodegenerative disease with severe memory loss, personality changes, unusual behavior and impairment in cognitive function. There is no cure for AD, and the drugs available for the treatment of the disease have limited efficacy. Medicine develops from the extract of medicinal plants have been the single most productive and common source for the development of drugs, and also, more than thousands of new products are already in clinical study. Different types of therapeutic strategies like herbal and synthetic approaches are being used against AD on the basis of understanding AD mechanisms. Ginkgo biloba extract (GBE) is the most effective and highly investigated, herbal medicine for AD and other cognitive disorders. One of the famous dietary supplements is GBE, consumed by the elderly population to improve memory and age-related loss of cognitive function. The exact mechanism of action of Ginkgo extract in AD is still not very clear. The phytochemical studies of the different plant parts of the G. biloba have revealed the presence of many valuable secondary metabolites, such as flavonoids, polyphenols, triterpenes, sterols, and alkaloids that shows a wide spectrum of pharmacological activities like anti-amyloidogenic, antiinflammatory and antioxidant effects. This book chapter gathers research on the G. biloba plant and its neuroprotective and phytochemical effects, which are used against AD. The summarized information concern pharmacological activities, neuroprotective effect, and biological and clinical applications of the Ginkgo plant. © 2022, Bentham Books imprint. All Rights Reserved.
