Silk-fibroin Grafted with Chitosan is a Promising Polymer-based Nanoparticle for Drug Delivery Abstract I. Introduction Drug delivery systems are crucial to promote the efficacy of pharmaceutical compounds, as these carriers contain the active drug. The drug can be dissolved, dispersed, encapsulated, absorbed, or attached to the carrier. Therefore, the material used in the composition of the…

Graphene sieves can turn seawater into drinking water by filtering common salts from water to make it safe to drink. Graphene-oxide membranes have attracted lots of attention for new filtration technologies. These findings came from a group of scientists at the University of Manchester that were published in the journal Nature Nanotechnology on the 4th…

Saliva can be secreted through two reflexes known as simple salivary reflex and conditioned reflex. Simple salivary reflex occurs when chemoreceptors are stimulated by the presence of food and send signal to the medulla oblongata which in turn signal the release of more saliva. The conditioned salivary reflex occurs when there is no oral stimulation….

Colour is usually the first contaminant to be recognized in a wastewater because a very small amount of synthetic dyes in water ( < 1 ppm) are highly visible, affecting the aesthetic merit, transparency and gas solubility of water bodies. They adsorb and reflect the sunlight entering water, thereby interfering with the aquatic species growth…

Hormones are organic substances that are secreted by plants and animals and that function in the regulation of physiological activities and in maintaining homeostasis. They carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they…

Squid are wild and wonderful. They are believed to be remarkably intelligent because of their apparently complex communication system. They include the Vampire Squid, and the elusive and mysterious Giant Squid. I researched the Giant Squid which is the biggest animals in the sea. The giant squid lives in most of the world`s oceans and…

A one of the oldest fibres used by human beings. Archaeologists have found cotton 5000 years old. Alexander the Great, around 300 BC, brought cotton goods into Europe but only the rich could afford it. The cotton plant grew wild in East Africa. Cotton belongs to the Hibiscus family. Our commercial varieties of cotton were…
