Materials & Methods Synthesis Procedure of PDA@MT Polydopamine is synthesized through covalent polymerization similar to melanin biosynthesis‚ with DA oxidized to dopamine quinone‚ then further oxidized to DHI‚ which undergoes deprotonation and cross-linking via Michael addition to form PDA. A solution was prepared to synthesize PDA by mixing 90 mL of water‚ 40 mL of ethanol‚ and 3 mL of ammonia solution in a 300 mL beaker. After stirring for 30 minutes at 37°C‚ a solution of 500 mg of DA dissolved

Stoichiometric Analysis Formal Lab Report I. Purpose- The purpose of this lab is to show stoiciometric reactions and relationships first hand. It also increases our level of understanding about the complicated relationships in chemical reactions and in stoichiometry. II. Introduction- In chemical reactions and formulas there are various relationships between masses of reactants and products. The study of these relationships is called stoichiometry which is derived from the Greek words stoichein

Identifying Organic Compounds Problem: Based on the color of the indicator‚ which type of organic compound will be found in each type of food? Hypothesis: If Benedict solution is added to honey‚ then it will turn. If Biuret solution is added to egg whites‚ then it will turn. If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter

Photolytic Degradation of Flupentixol-Melitracen Chapter One Introduction 1 Photolytic Degradation of Flupentixol-Melitracen 2 1. ANTIPSYCHOTIC 1.1 Antipsychotic An antipsychotic also known as neuroleptic is a tranquilizing psychiatric medication which is used to treat psychosis‚ schizophrenia and bipolar disorder. Now it is increasingly being used to treat the non-psychotic disorders. Psychosis disorder included delusions or hallucinations. Delusion is the pathological condition

In the reaction mechanism‚ a carboxylic acid‚ m-toluic acid is used to synthesize N‚N-diethyl-m-toluamide‚ also know as DEET‚ through a nucleophilic acyl substitution reaction. The reaction begins by first converting the m-toluic carboxylic acid into an acyl chlorosulfite through a reaction using thionyl chloride. The carboxylic acid is converted into an acyl chloride because the acyl chloride is more reactive. In this step‚ hydrochloric acid is formed from a hydrogen on the carboxylic acid and a

At the beginning of the lab‚ a micro test tube with and without glass wool was weighed on an analytical balance. A watch glass‚ crucible‚ and lid were also weighed. The masses of all the materials needed for the lab were recorded in the data tables of the laboratory notebook. An unknown vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica

Determining Allele Frequencies of the PV92 Alu Element using DNA Isolated from Human Cheek Cells and PCR Amplification Background Alu elements are the most abundant repetitive elements in the human genome that have mobilized throughout primate genomes by retrotransposition over the past 65 million years ago from a 5’ to 3’ fusion of the 7SL RNA gene‚ to reach the present number of more than one million copies. Over the last few years‚ several lines of evidence demonstrated that these elements
