The stratum corneum, the most superficial layer of the skin, protects the body against environmental hazards and presents a highly selective barrier for the passage of drugs and cosmetic products deeper into the skin and across the skin. Nanomaterials can effectively increase the permeation of active molecules across the stratum corneum and enable their penetration into deeper skin layers, often by interacting with the skin and creating the distinct sites with elevated local concentration, acting as reservoirs. The flux of the molecules from these reservoirs can be either limited to the underlying skin layers (for topical drug and cosmeceutical delivery) or extended across all the sublayers of the epidermis to the blood vessels of the dermis (for transdermal delivery). The type of the nanocarrier and the physicochemical nature of the active substance are among the factors that determine the final skin permeation pattern and the stability of the penetrant in the cutaneous environment. The most widely employed types of nanomaterials for dermal and transdermal applications include solid lipid nanoparticles, nanovesicular carriers, microemulsions, nanoemulsions, and polymeric nanoparticles. The recent advances in the area of nanomaterial-assisted dermal and transdermal delivery are highlighted in this review.

Abstract:Transdermal delivery offers an excellent route for drug and vaccine administration. Nonetheless, the lipid-rich outer stratum corneum layer of the skin presents a critical challenge to drug penetration. Laser ablation perforates epidermis through selective photothermolysis, making skin more permeable to hydrophilic and macromolecular drugs such as peptides, proteins, and genes. This review summarizes recent applications to laser ablation-enhanced transdermal delivery. Needle- and pain-free transcutaneous drug delivery via laser ablation provides an alternative approach to achieve local or systemic therapeutics.

Transdermal delivery offers opportunities for inventive, challenging and valuable research with patient benefits. However, the prominent challenge in designing transdermal drug delivery systems is to overcome the natural transport barrier of the skin, the stratum corneum. Several physical and chemical enhancement techniques have been investigated in the last decade to breach the skin barrier and assist the transport of macromolecules across skin. Recent technological advances in this field include novel combination strategies of penetration enhancement techniques, microneedle array designs, needle-free technologies, nanocarriers, metered dose and microstructured transdermal systems. The present review reports on recent advances in physical approaches towards enhanced transdermal penetration. Enhancement strategies comprehensively covered in this review emphasize the significant achievements gained through successful transdermal delivery of hydrophilic macromolecules, vaccines, proteins, peptides, oligonucleotides, fluorescent dyes and plasmid delivery. Some commercially available technologies for transdermal delivery have also been covered. These novel technologies hold immense potential to advance further into clinical practice and enable better therapeutic applications and prophylactic interventions for various diseases.
