    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

    Synthesis and Purification of Acetylsalicylic Acid (ASA or Aspirin) Background Salicylic acid is a phenol as well as a carboxylic acid. It can therefore undergo two different types of esterification reactions‚ creating an ester either with the hydroxyl or with the acid. In the presence of acetic anhydride‚ acetylsalicylic acid (aspirin or ASA) is formed. Correspondingly‚ an excess of methanol will form methyl salicylate‚ which is also an analgesic. In this experiment‚ we shall use

    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

    “The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

    Determining Genotypic Frequencies for Alu Insertion Polymorphism at the PV92 Locus Introduction An Alu element is a short stretch of non-coding DNA found in primates. It gets its name from the single recognition site for the endonuclease Alu I‚ located near the middle of the Alu element. Alu elements are transposable DNA sequences that copy and insert themselves into new chromosome locations. They are regarded as “selfish DNA” because they do not encode protein and appear to only exist for their

    Luminol solutions use oxidation reactions to create the bright‚ luminescent‚ blue emission. In order to discover which additive enhances that glow the most and for the longest‚ I studied the data of several tests with varying enhancers added to the luminol. The substances to be compared in this study are as follows: cysteine‚ Cu (II)‚ silver nanoparticles (AgNPs)‚ and zinc sulfide nanoparticles (ZnS-NPs). The first experiment focused on the reaction between alkaline luminol H2O2‚ the most common
