According to the research by the World Health Organisation (WHO), 36 million people die each year due to various health problems. However, this number can be reduced if patients are detected early and treated properly. The expansion and use of electronic nose have many applications in the healthcare, and a bio-medical field is rapid to accelerate over the past 25 years. Many e-nose technologies have given answers or provided results of complex biomedical and healthcare problems. The purpose of this review is to present the use of e-nose in the medical field, or how e-nose helps in detecting various diseases in human at an early stage so that it can be cured easily. E-nose is a device which is being developed as systems for the detection of miscellaneous odors. These odors can be of food, drinks, cosmetics, medicines, etc. With the help of an array of sensors placed inside it, detection is possible. Various diseases like lung cancer, asthma in children, diagnosis of illness by breathing analysis, prostate cancer,...

Improving oral bioavailability of drugs those used as solid dosage forms remains a challenge for the formulation scientists due to solubility problems associated with it. The dissolution rate could be the rate-limiting process in the absorption of a drug from a solid dosage form of relatively insoluble drugs. Solid dispersion techniques have attracted the considerable interest in improving the dissolution rate of highly lipophilic drugs, thereby improving their bioavailability by micronization, improving wettability and use of a surface active agent. The term solid dispersion refers to a cluster of solid products consisting of at least two different components, generally a hydrophilic inert carrier or matrix and a hydrophobic drug. This article reviews the historical background of solid dispersion technology, limitations, classification, and various preparation techniques with its advantages and disadvantages. This review also discusses the recent advances in the field of solid dispersion technology. The experience with solid dispersions over the last 10-15 years indicates that this is a very fruitful approach in improving the release rate and oral...

The technological development is leading the human life to be comfortable. It is also gaining important attention as per health concern as it has enhanced the survival of the patients. The development in technology has become a boon to human beings. Electronic Pill is one such technology that is used to strive in opposition to deadly diseases by detecting diseases and abnormalities in the human body. These electronic pills are swallow-able or implantable in the human body to detect biological signals or capture images that are to be used for diagnostic and therapeutic purposes. The sensor-based electronic pills (capsules) are used in modern days to carryout complex treatments and hence, are called to be Pharmacy-on-chip (POC). The concept involves having simple electronic devices that include sensors, drug delivery systems, or tissue simulating tools powered by the batteries. The technology has a range of applications in the detection of disease and abnormalities in medical research. The overall aim has been to deliver enhanced functionality, reduced size, and power consumption, through...

The RFID (Radio Frequency Identification) is a decade old wireless technology based on radio frequencies and is a member of Automatic Identification and Data Capture (AIDC) family. Its first application was seen around in the year 1945, and in recent years numerous applications have been evolved and are practically implemented in approximately every field. The motive of this work is to survey the different applications in the present scenario in the field of...
