まとめ
サトウキビ由来ナノセルロースコーティングは、サージカルマスク用のポリプロピレン不織布を強化します。これらの生体適合性コーティングは、マスク構造を変更せずに表面特性を向上させ、より優れた濾過の可能性を提供します。
科学分野:
- 材料科学; 生体材料工学; 表面化学
背景:
- ポリプロピレン(PP)不織布はサージカルマスクの濾過に不可欠ですが、その疎水性は機能化を妨げます。 機械的濾過と細孔径制御の改善には、PP不織布の不活性表面の改質が必要です。
研究 の 目的:
- サトウキビ廃棄物から得られるナノセルロースコーティングを開発し、PP不織布の表面を改質すること。 これらのナノセルロースコーティングの表面特性、接着性、および生体適合性を評価すること。
主な方法:
- サトウキビセルロースをセルロースナノファイバー(CNF)、TEMPO酸化ナノファイバー(TCNF)、およびカチオン性ナノファイバー(CCNF)に加工しました。 ナノファイバーの構造、熱安定性、表面電荷(ζ)、および濡れ性を特徴付けました。 PP不織布をナノセルロースで、エタノール前処理ありとなしで、ディップコーティングし、湿度下でのコーティングの均一性と接着性を分析しました。
主要な成果:
- TCNFおよびCCNFは、1重量%でPP不織布上に均一なコーティングを提供し、CCNFはPPの表面電荷を反転させ、湿度下でそれを維持しました。 エタノール前処理はCCNFの接着を強化し、湿潤条件下で連続したナノ多孔質フィルムを維持しました。 コーティングされたおよびコーティングされていない不織布は、検出可能な細胞毒性を示しませんでした。
結論:
- サトウキビ由来のナノセルロース、特にTCNFおよびCCNFは、PPマスク不織布の効果的な生体適合性コーティングです。 これらのコーティングは、材料の完全性や安全性を損なうことなく、表面特性を改質し、接着性を向上させます。 開発されたコーティングは、サージカルマスクの濾過性能を向上させる可能性を示しています。

Masking and Demasking Agents
3.5K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Oxygen Delivering System I: Nasal Cannula and Face Mask
1.6K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Clathrin Coated Vesicles
9.3K
Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...

COP Coated Vesicles
18.2K
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of...

Coat Assembly and GTPases
4.4K
Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection.
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...
