The synthesis and applications of ring-opening metathesis polymerization (ROMP) derived poly(olefins) have emerged as an exciting area of great interest in the field of biomaterials science. The major focus of this mini-review is to present recent advances in the synthesis of functional materials using ROMP-derived poly(olefins) utilized for drug release, sensing, and cellular uptake in the past seven years (2015-2022). This review reveals that materials synthesized by ROMP-derived well-defined functional poly(olefins) stand to be highly promising systems for medical as well as biological studies. Thus, this review may prove to be beneficial for the design and development of new smart and flexible-functionality ROMP-based polymeric materials for various biological applications.

Photoresponsive drug delivery systems have great potential for improved cancer therapy. However, most of the currently available drug-delivery nanosystems are relatively large and require light excitation with low tissue penetration. Here, we designed a near infrared responsive drug delivery system by loading [Ru(terpyridine)(dipyridophenazine)(HO)] (Ru(tpy)DPPZ) in azobenzene-modified mesoporous silica coated NaGdF:Nd/Yb/Tm upconversion nanoparticles (azo-mSiO-UCNPs).

In the contemporary era of drug discovery, herbal treatments have demonstrated an unparalleled ability to produce anticancer drugs. An important part of the therapy of cancer is the use of plants and their by-products via analogues, which alter the tumor microenvironment and several signaling pathways. The objective of the current investigation was to conclude the rate at which the herbal medications quercetin (QT) and sulforaphane (SFN) repressed the growth of breast carcinoma cells in MDA-MB-231 by preventing the ERK/MAPK signaling systems.

Antibiotic resistance has become a critical health crisis globally. Traditional strategies using antibiotics can lead to drug-resistance, while inorganic antimicrobial agents can cause severe systemic toxicity. Here, we have developed a dual-antibiotic hydrogel delivery system (PDA-Ag@Levo/CMCS), which can achieve controlled release of clinical antibiotics levofloxacin (Levo) and classic nanoscale antibiotic silver nanoparticles (AgNPs), effectively eliminating drug-resistant .
