Scholarly scientific journals and peer-reviewed journals are often viewed as credible sources that other scientists or researchers make references when writing their own dissertations or research reports. However, in order to gain credibility from academia, it is essential to follow certain guidelines and organization when writing a scientific paper. From the given scientific paper, Cytotoxic Activity of Biosynthesized Gold Nanoparticles with an Extract of the Red Seaweed Corallina officinalis on the MCF-7 Human Breast Cancer Line, I observed several sections that are imperative to the completeness and persuasiveness of the paper. The sequence of the specific sections are as follows: abstract, introduction, materials and methods, results,

The introduction section provides the background information required for this research. There are three major groups of knowledge in the introduction, which are facts and challenges of breast cancer, potentials and advantages of nanotechnology (i.e. GNPs), and the antitumor activity of various seaweed with a focus of C.officinalis. Scrutinizing from the introduction, we can also find that this paper zeroes in on breast cancer therapy and the GNPS’ ability to suppress MCF-7 cells. Also, references in this section function as supporting resources that supplement the background information. Most of these references are primary sources like “Nanotechnology has large potential in detection and treatment of cancer in its incipient stage (Singh and Nehru, …show more content…
Particularly, this section provides an chronological explanation of all the experimental steps, ranging from collecting sample C.officinalis, to investigating the characterizations and cytotoxic activity, and to conducting DNA fragmentation. When inspecting on the characterizations of GNPs, the researcher utilized an array of spectrum analysis such as UV-Vis spectral analysis and Energy-dispersive analysis X-ray to inspect different characteristics. In this spectrum analysis experiment, the researcher found the particle size and shape of GNPs by exposing GNPs under lights with different wavelengths. As for the investigation of GNPs’ antitumor activity, the researcher treated MCF-7 cells with different GNPs concentration, which are 6, 3, 1.5, 0.75, and 0.375l/ml. Moreover, this whole section is written in past tense, third person, and passive voice. In my opinion, writing in third person and passive voice makes this section look more objective and neutral, and past tense is a way to indicate that this experiment was already finished at the time of writing. For example, the researcher uses “The cells were examined on a daily basis” and “MCF-7 cells were suspended in 0.5 lysis
