Alginate Application in Drug Delivery
Alginates are generally used in the food, beverage, cosmetic, paper, textile printing, and pharmaceutical industries. They have been utilized as stabilizers, thickeners, emulsifiers, and hydration and gelling agents. The main use of alginate in the biomedical industry is mainly focused on hydrogels used in wound healing, drug delivery, and tissue regeneration. The broad range of applications is due to its biocompatibility, low toxicity and relatively low-cost consumption, and structural similarity to the extracellular matrices of living tissue.

Alginate Microparticles for Food, Pharmaceutical and Cosmetic Applications
Alginates are the most widely used natural polymers in the pharmaceutical, food and cosmetic industries. Usually, they are applied as a thickening, gel-forming and stabilizing agent. Moreover, the alginate-based formulations such as matrices, membranes, nanospheres or microcapsules are often used as delivery systems. Alginate microparticles (AMP) are biocompatible, biodegradable and nontoxic carriers, applied to encapsulate hydrophilic active substances, including probiotics.

Alginate-Based Biomaterials
Alginates are naturally occurring polysaccharides extracted from brown marine algae and bacteria. Being biocompatible, biodegradable, non-toxic and easy to gel, alginates can be processed into various forms, such as hydrogels, microspheres, fibers and sponges, and have been widely applied in biomedical field.

Alginate-Based Hydrogels and Scaffolds for Biomedical Applications
Alginate is a natural polymer of marine origin and, due to its exceptional properties, has great importance as an essential component for the preparation of hydrogels and scaffolds for biomedical applications. The design of biologically interactive hydrogels and scaffolds with advanced, expected and required properties are one of the key issues for successful outcomes in the healing of injured tissues. This review paper presents the multifunctional biomedical applications of alginate-based hydrogels and scaffolds in selected areas, highlighting the key effect of alginate and its influence on the essential properties of the selected biomedical applications.

Aliphatic Polyesters by ADMET Polymerization and Hydrogenation
The recent developments of the synthesis of bio-based long-chain aliphatic polyesters by the acyclic diene metathesis (ADMET) polymerization of α,ω-dienes, derived from plant oils and bio-based chemicals, like bis(10-undecenoate) with isosorbide, using ruthenium-carbene catalysts. The development of subsequent (one-pot) tandem hydrogenation produced saturated polyesters under mild conditions.

ALK Inhibitor
ALK inhibitors are anti-cancer drugs that act on tumours with variations of anaplastic lymphoma kinase (ALK) such as an EML4-ALK translocation. They fall under the category of tyrosine kinase inhibitors, which work by inhibiting proteins involved in the abnormal growth of tumour cells. All the current approved ALK inhibitors function by binding to the ATP pocket of the abnormal ALK protein, blocking its access to energy and deactivating it. A majority of ALK-rearranged NSCLC harbour the EML4-ALK fusion, although as of 2020, over 92 fusion partners have been discovered in ALK+ NSCLC. For each fusion partner, there can be several fusion variants depending on the position the two genes were fused at, and this may have implications on the response of the tumour and prognosis of the patient.

Alkyl Chains Impact in Polymer-Based organic Solar Cells
The research for efficient organic materials organized in bulk heterojunction (BHJ) thin films for organic photovoltaics (OPVs) has shown a significant breakthrough. Desired structural organization can be attained through various strategies. Conjugated polymer-based bulk heterojunction solar cells have exhibited high power conversion efficiencies (PCEs). The role of side chain engineering in solution-processable conjugated polymers is taking a growing role in these record performances.

All-Cellulose Composites
Wood- or plant-based cellulose fibres have shown their potential as a reinforcement in composites for a relatively long time alongside the commonly used glass-fibre and carbon-fibre reinforcements. Whereas regular biocomposites suffer from fibre-matrix adhesion-related challenges, all-cellulose composites (ACCs) can overcome this problem by both matrix and reinforcement having the same or a similar chemical structure, which results in good interfacial compatibility. ACCs can provide an environmentally friendly alternative to conventional petrochemical-based materials since they are a type of single-polymer composites (SPCs) from biomass-derived cellulose, and as such, they are easily recyclable, and they originate from renewable sources.
