    (Mdpi, 2024) Eker, Furkan; Duman, Hatice; Akdasci, Emir; Bolat, Ecem; Saritas, Suemeyye; Karav, Sercan; Witkowska, Anna Maria
    Nanoparticles are structures that possess unique properties with high surface area-to-volume ratio. Their small size, up to 100 nm, and potential for surface modifications have enabled their use in a wide range of applications. Various factors influence the properties and applications of NPs, including the synthesis method and physical attributes such as size and shape. Additionally, the materials used in the synthesis of NPs are primary determinants of their application. Based on the chosen material, NPs are generally classified into three categories: organic, inorganic, and carbon-based. These categories include a variety of materials, such as proteins, polymers, metal ions, lipids and derivatives, magnetic minerals, and so on. Each material possesses unique attributes that influence the activity and application of the NPs. Consequently, certain NPs are typically used in particular areas because they possess higher efficiency along with tenable toxicity. Therefore, the classification and the base material in the NP synthesis hold significant importance in both NP research and application. In this paper, we discuss these classifications, exemplify most of the major materials, and categorize them according to their preferred area of application. This review provides an overall review of the materials, including their application, and toxicity.

    Functional chocolate: exploring advances in production and health benefits
    (Wiley, 2024) Saritas, Suemeyye; Duman, Hatice; Pekdemir, Burcu; Rocha, Joao Miguel; Oz, Fatih; Karav, Sercan
    Chocolate has been a part of human consumption for millennia, serving as a confection, medicine and aphrodisiac. Chocolate consumption is increasing worldwide, and independent of the age or social background. The substantial content of chocolate may provide consumers with antioxidant, anti-inflammatory, antimicrobial, antiallergenic, and anticarcinogenic benefits. Beyond such properties, diverse bioactive ingredients are utilised in the creation of functional chocolate products aiming at promoting health and meeting the modern consumers' demands and market orientations. These products are primarily focused on enhancing nutraceutical effects, such as antioxidant activity, protein content and prebiotic effects. Additionally, the use of A2 milk powder in chocolate production holds promising expectations towards enhancing the digestibility of the products. Due to the superior affinity of proteolytic enzymes, A2 milk can be digested more easily than A1 milk. In this way, with the addition of A2 milk to chocolate, it may become more easily digestible. The objectives of this review are a comprehensive understanding of the evolution of chocolate consumption, its health benefits, and the contemporary innovations in chocolate production. Additionally, the potential for developing easily digestible, functional chocolates made from A2 milk, which could rejuvenate functional chocolate production, is discussed in this article. The bioactive components contained in various types of chocolate have been shown in the graphical abstract. The bioactive components and amounts contained vary according to the type of chocolate. image

    Lactoferrin for COVID-19 prevention, treatment, and recovery
    (Frontiers Media Sa, 2022) Bolat, Ecem; Eker, Furkan; Kaplan, Merve; Duman, Hatice; Arslan, Aysenur; Saritas, Suemeyye; Sahutoglu, Arif Sercan
    Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), a unique beta-coronavirus, has caused the most serious outbreak of the last century at the global level. SARS-CoV-2 infections were firstly reported in the city of Wuhan in China in 2019 and this new disease was named COVID-19 by World Health Organization (WHO). As this novel disease can easily be transmitted from one individual to another via respiratory droplets, many nations around the world have taken several precautions regarding the reduction in social activities and quarantine for the limitation of the COVID-19 transmission. SARS-CoV-2 is known to cause complications that may include pneumonia, acute respiratory distress syndrome (ARDS), multi-organ failure, septic shock, and death. To prevent and treat COVID-19, some significant studies have been conducted since the outbreak. One of the most noticeable therapeutic approaches is related to a multifunctional protein, lactoferrin. Lactoferrin (Lf) is an 80 kDa cationic glycoprotein that has a great range of benefits from improving the immunity to antiviral effects due to its unique characteristics such as the iron-binding ability. This review summarizes the characteristics of SARS-CoV-2 and the potential applications of Lf for the prevention, treatment, and recovery of COVID-19.
