Among all the computational techniques (Density Functional Theory, Molecular Dynamics, Monte-Carlo Simulations, Nanothermodynamics) used to investigate the properties of nanoparticles, nanothermodynamics is the most unusual one. Indeed, most people still thing that thermodynamics does not apply at the nanoscale; nonetheless, thermodynamic concepts can still be applied at the nanoscale to predict various properties of nanoparticles like melting temperature, energy bandgap . . . In this review, we first introduce the fundamental concepts and methods of nanothermodynamics starting from Hill's contributions to the most recent developments focusing specifically on the relationship between the material property and the following parameters as quantum statistics (Fermi-Dirac or Bose-Einstein), size and shape of the nanoparticle.

“…It was determined that inhibition occurred via adherence and penetration of the nanoparticles to the cells and subsequently damages the cellular structures. Therefore, crystallinity and small size allows easy conjugation and penetration in to the biofilm surface leading to better inhibition [15]. We thus envision that QDs could be considered as practical probes for investigating candidiasis infection, biofilm imaging and treatment.…”

High toxicity, low host tolerance, narrow spectrum of antifungal drugs and increasing incidence of azole-resistance complicates treatment of invasive Candida infections. Due to the emergence of antimicrobial resistance as an increasing threat to global health care, arises the need to develop new, and effective broad spectrum active antifungal agents. Thus understanding and combating drug resistance in Candida albicans is a toughest challenge being faced today and it's immensely important to develop an alternative coating that can inhibit biofilm formation on medical devices as implants and catheters. Additionally, the fascinating properties of nanomaterials and biocompatibility promises great potential in nanomedical applications, especially in medical microbiology. With appropriate modification of these synthetic materials, several disease infections can be cured and results have shown the use of these nanomaterials as diagnostic and immunotherapauetic agents. Since, antimicrobial resistance is becoming a major apprehension worldwide, nanomedicines offer an intriguing and promising solution for combating these high resistance pathogens by appropriate development of therauptic and novel diagnosis approaches. This mini review presents the current state of art in this emerging field.

Infection of implants by microbial biofilm is chiefly caused by Staphylococci, Pseudomonas andCandida species. The growth of microbes by forming biofilms offers them protection from antibiotics, drugs and host defense mechanisms. The eradication of biofilms from implants and medical devices is difficult because of the protection by the biofilm forming pathogenic microbes. Hence, researches are focused on development of antibiofilm materials, which are basically constituted of antimicrobial substances or antimicrobial coatings. Nanomaterialbased coatings offer a promising solution in this regard. Quantum dots (QDs) are the group of semiconductor nanoparticles with high photoluminescent properties compared to conventional organic fluorophores. Thus, drug-conjugated QDs can be a promising alternative for biofilm treatment, and these can serve as excellent alternatives for the mitigation of recalcitrant biomaterial-associated infections caused by resistant strains. Furthermore, their use as antibiofilm coating would avoid the dispersion of antimicrobial agents in the surrounding cells and tissues, thereby minimizing the risks of developing microbial resistivity.
