Abstract

The study of tiny particles and their applications have emerged as an important area of research in recent years. In particular, magnetic nanoparticles have attracted considerable attention due to their unique properties that make the particles useful in numerous applications. Accordingly, the present review investigates the synthesis, characterization, and biomedical applications of magnetic nanoparticles. The introduction section examines recent advances in nanotechnology and explains the significance of magnetic nanoparticles in scientific research. The section on results and discussion presents the findings of various researchers with a focus on the magnetic properties, synthesis, characterization, and biomedical applications of magnetic nanoparticles. ...

Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

Gold Nanoparticles Article Summaries.

Original Article Summary: Turkevich, Stevenson, & Hillier, 1951. In their 1951 article, Turkevich, Stevenson, and Hillier explore the nucleation processes and growth of colloidal gold nanoparticles during synthesis under different methods. The paper explores the standard preparation methods of colloidal gold which all use a nucleating agent which usually comprises reducing agents that later form a mixed polymer with a chloroauric ion before reduction to the nucleus occurs. The authors of this paper explore gold colloids synthesis methods such as Bredig’s electrical arc synthesis, the Faraday method, and reduction methods using acetone, tannin gold solution, oxalic acid, Hydroxylamine hydrochloride, ...

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 ...

1. Introduction

Taste is a chemical reaction from sensory response of four main taste perceptions sweet, bitter, sour and salt. In the pharmaceutical industry oral administration is the most popular method of drug delivery and most of the drugs elicit bitter taste. Taste is an important factor in determining the drug palatability which in turn is vital in ensuring the consumers compliance in taking the drug and hence effective chemotherapy. In addition, in the ever competitive market, organoleptic properties (test, mouth feel and smell) are vital factors in marketing of drugs. Thus taste masking technology is an important factor in ensuring high ...
