To manage the COVID-19 pandemic, development of rapid, selective,
sensitive diagnostic systems for early stage β-coronavirus
severe acute respiratory syndrome (SARS-CoV-2) virus protein
detection is emerging as a necessary response to generate the
bioinformatics needed for efficient smart diagnostics,
optimization of therapy, and investigation of therapies of
higher efficacy. The urgent need for such diagnostic systems is
recommended by experts in order to achieve the mass and targeted
SARS-CoV-2 detection required to manage the COVID-19 pandemic
through the understanding of infection progression and timely
therapy decisions. To achieve these tasks, there is a scope for
developing smart sensors to rapidly and selectively detect
SARS-CoV-2 protein at the picomolar level. COVID-19 infection,
due to human-to-human transmission, demands diagnostics at the
point-of-care (POC) without the need of experienced labor and
sophisticated laboratories. Keeping the above-mentioned
considerations, we propose to explore the compartmentalization
approach by designing and developing nanoenabled miniaturized
electrochemical biosensors to detect SARS-CoV-2 virus at the
site of the epidemic as the best way to manage the pandemic.
Such COVID-19 diagnostics approach based on a POC sensing
technology can be interfaced with the Internet of things and
artificial intelligence (AI) techniques (such as machine
learning and deep learning for diagnostics) for investigating
useful informatics via data storage, sharing, and analytics.
Keeping COVID-19 management related challenges and aspects under
consideration, our work in this review presents a collective
approach involving electrochemical SARS-CoV-2 biosensing
supported by AI to generate the bioinformatics needed for early
stage COVID-19 diagnosis, correlation of viral load with
pathogenesis, understanding of pandemic progression, therapy
optimization, POC diagnostics, and diseases management in a
personalized manner.
The recent advancements of Internet of Things (IoT) embedded systems, wireless networks, and biosensors those have assisted in the rapid development of implanting wearable sensors are reviewed here. The applications of the internet of medical things (IoMT) that has gained major attention as an ecosystem of connected clinical systems, computing systems, and medical sensors geared towards improving the quality of healthcare services are also reviewed here. The 5G based AI technology can revolute the perception of healthcare and lifestyle. In light of the importance of IoT platforms and 5G networks, the purpose of this proposed research work is to identify threats that could undermine the integrity, privacy, and security of IoMT systems. Also, the novel blockchain‐based approaches that can help in improving the confidentiality of IoMT network. It has been discovered that IoMT is vulnerable to various types of attacks, including denial of service (DoS), malware, and eavesdropping attack. In addition, IoMT is exposed to various vulnerabilities, such as security, privacy, and confidentiality. Despite multiple security threats, there are novel cryptographic techniques, such as access control, identity authentication, and data encryption that can help in improving the security and reliability of IoMT devices.
The emergence of new SARS-CoV-2 variants made the COVID-19 infection pandemic and/or endemic more severe and life-threatening due to ease of transmission, rapid infection, high mortality, and capacity to neutralize the therapeutic ability of developed vaccines. These consequences raise questions on established COVID-19 infection management strategies based on nano-assisted approaches, including rapid diagnostics, therapeutics, and efficient trapping and virus eradication through stimuli-assisted masks and filters composed of nanosystems. Considering these concerns as motivation, this perspective article highlights the role and aspects of nano-enabled approaches to manage the consequences of the COVID-19 infection pandemic associated with newer SARS-CoV-2 variants of concern and significance generated due to mutations. The controlled high-performance of a nanosystem seems capable of effectively detecting new variables for rapid diagnostics, performing site-specific delivery of a therapeutic agent needed for effective treatment, and developing technologies to purify the air and sanitizing premises. The outcomes of this report project manipulative, multifunctional nanosystems for developing high-performance technologies needed to manage consequences of newer SARS-CoV-2 variants efficiently and effectively through an overall targeted, smart approach.
It has been proven that rapid bioinformatics analysis according to patient health profiles, in addition to biomarker detection at a low level, is emerging as essential to design an analytical diagnostics system to manage health intelligently in a personalized manner. Such objectives need an optimized combination of a nano-enabled sensing prototype, artificial intelligence (AI)-supported predictive analysis, and Internet of Medical Things (IoMT)-based bioinformatics analysis. Such a developed system began with a prototype demonstration of efficient diseases diagnostics performance is the future diseases management approach. To explore these aspects, the Special Issue planned for the nano-and micro-technology section of MDPI’s Biosensors journal will honor and acknowledge the contributions of Prof. B.D. Malhotra, Ph.D., FNA, FNASc has made in the field of biosensors.
Australia faces a dryness disaster whose impact may be mitigated by rainfall prediction. Being an incredibly challenging task, yet accurate prediction of rainfall plays an enormous role in policy making, decision making and organizing sustainable water resource systems. The ability to accurately predict rainfall patterns empowers civilizations. Though short-term rainfall predictions are provided by meteorological systems, long-term prediction of rainfall is challenging and has a lot of factors that lead to uncertainty. Historically, various researchers have experimented with several machine learning techniques in rainfall prediction with given weather conditions. However, in places like Australia where the climate is variable, finding the best method to model the complex rainfall process is a major challenge. The aim of this paper is to: (a) predict rainfall using machine learning algorithms and comparing the performance of different models. (b) Develop an optimized neural network and develop a prediction model using the neural network (c) to do a comparative study of new and existing prediction techniques using Australian rainfall data. In this paper, rainfall data collected over a span of ten years from 2007 to 2017, with the input from 26 geographically diverse locations have been used to develop the predictive models. The data was divided into training and testing sets for validation purposes. The results show that both traditional and neural network-based machine learning models can predict rainfall with more precision.
