At present, aerogel is one of the most interesting materials globally. The network of aerogel consists of pores with nanometer widths, which leads to a variety of functional properties and broad applications. Aerogel is categorized as inorganic, organic, carbon, and biopolymers, and can be modified by the addition of advanced materials and nanofillers. Herein, this review critically discusses the basic preparation of aerogel from the sol–gel reaction with derivation and modification of a standard method to produce various aerogels for diverse functionalities. In addition, the biocompatibility of various types of aerogels were elaborated. Then, biomedical applications of aerogel were focused on this review as a drug delivery carrier, wound healing agent, antioxidant, anti-toxicity, bone regenerative, cartilage tissue activities and in dental fields. The clinical status of aerogel in the biomedical sector is shown to be similarly far from adequate. Moreover, due to their remarkable properties, aerogels are found to be preferably used as tissue scaffolds and drug delivery systems. The advanced studies in areas including self-healing, additive manufacturing (AM) technology, toxicity, and fluorescent-based aerogel are crucially important and are further addressed.

Traditional medicines that are derived mainly from herbaceous plants are widely used for years in many regions of the world. Currently, the world is facing the emergence of resistant microorganisms due to the overuse and misuse of antibiotics and the lack of new drug development. In consequence, the discovery of natural phytochemicals that are safe, cheap, non-toxic, and readily available would be an acceptable alternative source. Turmeric, scientifically known as Curcuma longa, in the family of Zingiberaceae (ginger) is well known for its diverse therapeutic properties. The medicinal properties of turmeric include antioxidant, anti-inflammatory, anti-microbial, anti-carcinogenic, cardioprotective, gastroprotective, hepatoprotective, and many more. Numerous studies have shown that curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione), which is the most active compound of turmeric, plays a significant role as a therapeutic agent. The present article provides a brief overview of the plethora of research regarding the medicinal properties of golden spice (turmeric), specifically of curcumin's role in the treatment of various illnesses. Interestingly, turmeric might play a role in protecting COVID-19 patients against the development of lung injury caused by cytokine storms. Hence, this warrants further scientific research to monitor the anti-inflammatory effect of turmeric on SARS-CoV-2.
