Per- and Polyfluoroalkyl Substances
Per- and polyfluoroalkyl substances (PFAS) are a family of synthetic fluorinated organic compounds whose widespread use and resistance to biodegradation have led to their accumulation in the environment, causing growing concerns over their impact on humans.

Applications of Graphene Oxide (GO) Materials
Graphene-based materials, due to their high sensitivity, inexpensive, fast response and simple operation, are utilized in the fabrication of biosensors based on various sensing methods, such as optical and electrochemical signaling. These materials are successful electrode materials due to their electrochemical characteristics, which can enhance the detection of biomoleculessuch as thrombin, oligonucleotides, ATP, amino corrosives, and dopamine. Biomolecules have an essential duty in all life activities, such as disease development, so the precise identification of biomolecules is necessary for disease diagnosis and therapy.

Carbon Nanofibers
Carbon nanofibers are nano-sized fibers that have a high degree of crystalline orientation. In recent years, ecological issues have led to the search for new green materials from biomass as precursors for producing carbon materials. Such green materials are more attractive than traditional petroleum-based materials, which are environmentally harmful and non-biodegradable.

Unsaturated Fat
An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. Where double bonds are formed, hydrogen atoms are subtracted from the carbon chain. Thus, a saturated fat has no double bonds, has the maximum number of hydrogens bonded to the carbons, and therefore is "saturated" with hydrogen atoms. In cellular metabolism, unsaturated fat molecules contain somewhat less energy (i.e., fewer calories) than an equivalent amount of saturated fat. The greater the degree of unsaturation in a fatty acid (i.e., the more double bonds in the fatty acid) the more vulnerable it is to lipid peroxidation (rancidity). Antioxidants can protect unsaturated fat from lipid peroxidation.

Conjugated Block Copolymers
Conjugated block copolymers (cBCPs) refer to block copolymers that contain one or more conjugated polymer segments. It can be a combination of several conjugated polymer segments with different properties, or it can be a combination of conjugated polymer segments and non-conjugated polymer segments. cBCPs not only maintain the advantages of high conductivity and mobility of conjugated polymers, but also demonstrate features of morphological versatility and tunability of block copolymers. cBCPs have a great potential application in organic solar cells, organic field effect transistors, organic light-emitting diodes and other fields.

Mitochondria-Targeted Drug in Cardiovascular Disease
Cardiovascular disease (CVD) represents a major threat for human health. The available preventive and treatment interventions are insufficient to revert the underlying pathological processes, which underscores the urgency of alternative approaches. Mitochondria dysfunction plays a key role in the etiopathogenesis of CVD and is regarded as an intriguing target for the development of innovative therapies. Oxidative stress, mitochondrial permeability transition pore opening, and excessive fission are major noxious pathways amenable to drug therapy. Thanks to the advancements of nanotechnology research, several mitochondria-targeted drug delivery systems (DDS) have been optimized with improved pharmacokinetic and biocompatibility, and lower toxicity and antigenicity for application in the cardiovascular field.

Hard Tissue Engineering
Hard tissues, e.g., bone, are mechanically stiff and, most typically, mineralized. To design scaffolds for hard tissue regeneration, mechanical, physico-chemical and biological cues must align with those found in the natural tissue. Combining these aspects poses challenges for material and construct design.  They can be fulfilled in top-down tissue engineering or bottom up biofabrication approaches upon employing biomaterials e.g. silk.

Fabrication Processes of Conductive Textiles
Wearable electronics are gaining popularity as a platform for the next generation of human-friendly electronic devices. Therefore, a new class of devices with various functionality and amenability for the human body is essential. Traditional textile materials, such as fiber, yarn, and fabric, are non-conductive. Innovative methods and novel processing technologies have been introduced to impart conductivity in textile materials to solve this issue. Coating, printing, deposition, and in situ polymerization are common techniques for this purpose. Here, the newly developed methods with significant potential are summarized, which includes their conductivity level in different applications, such as batteries, displays, and sensors.
