For many decades, Hemoglobin-based oxygen carriers (HBOCs) have been central in the development of resuscitation agents that might provide oxygen delivery in addition to simple volume expansion. Since 80% of the world population lives in areas where fresh blood products are not available, the application of these new solutions may prove to be highly beneficial (Kim and Greenburg 2006). Many improvements have been made to earlier generation HBOCs, but various concerns still remain, including coagulopathy, nitric oxide scavenging, platelet interference and decreased calcium concentration secondary to volume expansion (Jahr et al. 2013). This review will summarize the current challenges faced in developing HBOCs that may be used clinically, in order to guide future research efforts in the field.

The natural extracellular hemoglobin of the lugworm Arenicola marina (AmHb) has many interesting characteristics: It carries 40 times more oxygen than human hemoglobin; has anti-inflammatory, antibacterial, and antioxidant properties; and is 250 times smaller than a red blood cell. It is nontoxic and nonimmunogenic. It is thus a very promising hemoglobin-based oxygen carrier.

The creation of innovative ultrasound contrast agents (UCAs) with the ability to monitor oxygen levels in real-time holds immense potential for advancing early diagnosis of various medical conditions such as hypoxic/reperfusion injury. In this study, we propose the development of oxygen sensitive UCAs using microbubbles composed of hemoglobin (HbMBs), which can function as sensors for blood oxygen levels. Previously, we performed a study highlighting the initial proof-of-concept efficacy of air-filled HbMBs in detecting oxygenation changes in vitro, offering a promising tool for clinically detecting tissue hypoxia.

The limitations of traditional blood supply systems, particularly where ideal storage is unfeasible, challenge the efficacy of transfusion medicine, especially in emergencies and battlefield scenarios. This study investigates a novel hemoglobin-based oxygen carrier (HBOC) using a dual-coating approach with metal phenolic networks (MPNs) and polyethylene glycol (PEG). Utilizing zeolitic imidazolate framework-8 (ZIF-8) nanoparticles for their porosity and biocompatibility, the addition of MPN and PEG coatings enhances biocompatibility and stabilizes encapsulated hemoglobin (Hb).
