Essays on Nanomedicine

Over the last decade, the healthcare arena that includes research, education, and patient care has become overloaded with technological advances. Technology influences how nurses are educated, the way how they practice, provide and document patient care. Clinical Information Systems has already replaced paper and pencil input of information that helped to reduce errors and provide flexibility in delivering specific patient care. Vital signs including temperature and blood pressure are taken, recorded and tracked electronically, and nurses are alerted to any worrying and abnormal results. Moreover, POC bar coding, electronic medical records (EMR), personal data assistants (PDAs), and the health ...

Introduction

Studies relating to lung cancer treatment can save lives and make the lives of cancer patients more comfortable besides increasing the quality of life. According to Lardinois et al., (2003), there are three primary types of lung cancer; they include non-small cell, small cell, and carcinoid lung cancer. Statistically, non-small cell lung cancer, for example, Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma account for the highest occurrences of all lung cancers to a tune of 85% [1]. It has been established that both environmental and genetic factors do contribute to lung cancer significantly. Continued exposure to carcinogens, ionizing ...

Introduction

Research in lung cancer treatment can save lives and improve a patient’s quality of life. There are three main types of lung cancer: Non-small cell, small cell, and lung carcinoid cancer. Non-small cell lung cancer, such as Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma make up about 85% of all lung cancers (Molina, Yang, Cassivi, Schild, & Adjei, 2008). Both environmental and genetic factors are significant in the cause of lung cancer. Chronic exposure to carcinogens, ionizing radiation, and viral infections can lead to alterations of the DNA in tissue lining the bronchial epithelium of the lungs. Furthermore, ...

Introduction

Nanotechnology refers to the dimension of technology that deals with tolerances and dimensions of less than 100 nanometers (one billionth of a meter) especially in the manipulation of individual atoms and molecules. Nanobots are part of nanotechnology dealing with very tiny robots whose sizes are in the range of nanometer (10-9M). Although these tiny robots do not exist as yet, research is ongoing in producing these micro machines for among others functions molecular manufacturing and in the medical field.

Ethical dilemma

The major ethical dilemmas with nanobots involve their potential misuse by malicious entities to invade into privacies, potential for use ...

{Author Name [first-name middle-name-initials last-name]} {Institution Affiliation [name of Author’s institute]} All drug delivery systems (DDS) use the nanostructures as drug containers. There are various types of these nanocontainers such as polymeric liposomal nanoparticles, carbon nanostructures, magnetic nanoparticles and polymeric micelles (Singh and Lillard, 2009; Zarogoulidis et al., 2012). The mode of action of these nanostructures on the target site and the molecular proceedings occurring during this process provides a mechanistic foundation for drug discovery against cancerous developments. The several considerable points that an anti-cancer agent should have are targeted delivery to the impacted cells, least activity loss, ...

Introduction

Nanotechnology is a new venture for engineering field and has been seen as a breakthrough regarding materials thus providing a greater opportunity in enhancing both innovations as well as discovery in engineering and science fields. The primary application within the engineering sector have been; to create room for new nanofabrication technologies to improve nanostructures designing and construction which have by-passed the current technology. Additionally, it provides a chance to apply nanostructures in various devices such as magnets, optics, electronics and biotechnology devices (Dvir et al., 13-22). The opportunity is significant because the technology enhances innovation of materials as well ...
