The development of reliable and robust diagnostic tests is one of the most efficient methods to limit the spread of coronavirus disease 2019 (COVID-19), which is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). However, most laboratory diagnostics for COVID-19, such as enzyme-linked immunosorbent assay (ELISA) and reverse transcriptase-polymerase chain reaction (RT-PCR), are expensive, time-consuming, and require highly trained professional operators. On the other hand, the lateral flow immunoassay (LFIA) is a simpler, cheaper device that can be operated by unskilled personnel easily. Unfortunately, the current technique has some limitations, mainly inaccuracy in detection. This review article aims to highlight recent advances in novel lateral flow technologies for detecting SARS-CoV-2 as well as innovative approaches to achieve highly sensitive and specific point-of-care testing. Lastly, we discuss future perspectives on how smartphones and Artificial Intelligence (AI) can be integrated to revolutionize disease detection as well as disease control and surveillance.

: The possible beneficial properties of functional foods are due to their content in bioactive ingredients, with specific biological properties. A number of processed functional foods are available in the market – probiotic yogurt, calcium and ω-3 fatty acids enriched orange juice and milk. Simultaneously, new research studies confer potential health benefits of various conventional foods (salmon, berries, green tea, vegetables, fruits, nuts, cereals and breads etc) termed as “superfood” which is a marketing term and there is no established medical definition. Following suitable dietary patterns superfood reduces the risk of degerative diseases by promoting physical and emotional health. Scientific evidences suggests that superfood are dense source of antioxidants, minerals, vitamins and other nutrients. There is insufficient research on the exact explanation of term ‘superfood’and its health claims by different companies without any legislation. This buzz word making confusion among consumers, that how much and what quantity should make a food superfood, as no single food may be as nutritious to be stated as superfood. This article introduces further investigation on superfood which was categorized on the basis of their major constituents and potential health benefits. Further there is a need of more reviews, researches, clinical trials and human case studies to investigate or test superfood.

Diffusion of Innovation (DOI) theory explains how, over a period of time, an idea or behavior diffuses (or spreads) through a targeted population or society. The major thing about adoption is that the people must perceive the idea, behavior, or product as new or innovative and it should be useful to them. The more the perceived benefit, the quicker is the diffusion. Same thing can be expected for adoption of new technology in healthcare also. In this paper, we have described two novel breast cancer screening technologies and have concluded that implementation of a new technology should consider the cultural aspect and mindset of local people so that quick diffusion of healthcare technology takes place among all segments in our society to make it a better world.
